*10 points!* Honestly, I'm 100% serious -- how would I know if I was part dinosaur? *10 points!*?

Question

Not only do I bear a striking resemblance to a T-Rex, but whenever I see a man that catches my eye, I have to fight the urge to make mating calls. I also feel like I have a phantom tail. You know when people who lose their legs or arms in an accident can still feel the arm of leg? Well, I can still feel my tail, but I wasn't even born with one! I don't know if this is kind of a mental condition, or if I could truly be part dino. I also have oddly stunted arms (they're scrawny), and thick thighs. I know that that's what T-Rexes have, so maybe it's more of a biological condition instead of a mental one? What do you think?

I swear that I am 100% serious; please do not joke about this!

Answer 1

I think its a chemical thing. Honestly. When I was "in heat" for a guy, dude I am so ALPHA Female its scary. Like a T-Rex or Shark voracious! I have mellowed now, but in my late teens and twenties, god help the woman in the way, she was "spam" meat on my to the main course of that man.

Answer 2

woudnt dream of joking... maybe you like t rexes alot, i dont know if humans could have come trexes because i douth humans and dinasours would breed at any point plus there would be so many other people out there that feel the same... dont know what to say lol

Answer 3

You seem to be a tad delusional, no offense meant. I think you'd be wise to see a professional and tell them these facts. Have you spoken with your parents? Please get some help ASAP
This could be a good yarn your spinning for us but I choose to give you the benefit of the doubt and take your question seriously. If you've "pulled our leg" well done.

Answer 4

Get a DNA test.

Answer 5

One sure test....did you cry during "Jurassic Park?"

Answer 6

Well your off to a good start with the basics of the Trex, but if you are really going to determine if you are a partial one you need to consider the following factors as well. If you meeting the rest of the criteria then you are in fact the lost predator:
Sexual dimorphism
As the number of specimens increased, scientists began to analyze the variation between individuals and discovered what appeared to be two distinct body types, or morphs, similarly to some other theropod species. As one of these morphs was more solidly built, it was termed the 'robust' morph while the other was termed 'gracile.' Several morphological differences associated with the two morphs were used to analyze sexual dimorphism in Tyrannosaurus rex, with the 'robust' morph usually suggested to be female. For example, the pelvis of several 'robust' specimens seemed to be wider, perhaps to allow the passage of eggs.[29]
It was also thought that 'robust' animals possessed a reduced chevron on the first tail vertebra, also ostensibly to allow eggs to pass out of the reproductive tract, as had been reported for crocodiles.[30] However, in recent years, evidence for sexual dimorphism has been weakened. A full-sized chevron was discovered on the first tail vertebra of "Sue," an extremely robust individual, indicating that this feature could not be used to differentiate the two morphs. In 2005, it was reported that crocodiles exhibited no sexual dimorphism in chevron anatomy either, further weakening the case for dimorphism between T. rex sexes.[31] As T. rex specimens have been found from Saskatchewan to New Mexico, differences between individuals may be more indicative of geographic variation rather than sexual dimorphism. The differences could also be age-related, with 'robust' individuals being older animals.[1]
Only a single T. rex specimen has been conclusively shown to belong to a specific gender. Examination of "B-rex," the geologically oldest known specimen, demonstrated the preservation of soft tissue within several bones. Some of this tissue has been identified as medullary tissue, a specialized tissue grown only in modern birds as a source of calcium for the production of eggshell during ovulation. As only female birds lay eggs, medullary tissue is only found naturally in females, although males are capable of producing it when injected with female reproductive hormones like estrogen. This strongly suggests that "B-rex" was female, and that she died during ovulation. The presence of medullary tissue also provides further evidence of the close evolutionary relationship between birds and theropod dinosaurs.[27]
Like many bipedal dinosaurs, Tyrannosaurus rex was historically depicted as a 'living tripod', with the body at 45 degrees or less from the vertical and the tail dragging along the ground, similar to a kangaroo. This concept dates from Joseph Leidy's 1865 reconstruction of Hadrosaurus, the first to depict a dinosaur in a bipedal posture.[32] Henry Fairfield Osborn, former president of the American Museum of Natural History (AMNH) in New York City, who believed the creature stood upright, further reinforced the notion after unveiling the first complete T. rex skeleton in 1915. It stood in this upright pose for nearly a century, until it was dismantled in 1992.[33] By 1970, scientists realized this pose was incorrect and could not have been maintained by a living animal, as it would have resulted in the dislocation or weakening of several joints, including the hips and the articulation between the head and the spinal column.[34] Despite its inaccuracies, the AMNH mount inspired similar depictions in many films and paintings (such as Rudolph Zallinger's famous mural The Age Of Reptiles in Yale University's Peabody Museum of Natural History) until the 1990s, when films such as Jurassic Park introduced a more accurate posture to the general public. Modern representations in museums, art, and film show T. rex with its body approximately parallel to the ground and tail extended behind the body to balance the head.[11] There have been suggestions that, when chasing prey, the animal might have raised its neck into an 'S' position (much like that of a bird) in order to avoid problems in changing direction; this was discussed in The Truth About Killer Dinosaurs. This way, the head might not always have been jutting forwards.
When Tyrannosaurus rex was first discovered, the humerus was the only element of the forelimb known.[35] For the initial mounted skeleton as seen by the public in 1915, Osborn substituted longer, three-fingered forelimbs like those of Allosaurus.[23] However, a year earlier, Lawrence Lambe described the short, two-fingered forelimbs of the closely-related Gorgosaurus.[36] This strongly suggested that T. rex had similar forelimbs, but this hypothesis was not confirmed until the first complete T. rex forelimbs were identified in 1989, belonging to MOR 555 (the "Wankel rex").[37] The remains of "Sue" also include complete forelimbs.[1] T. rex 'arms' are very small relative to overall body size, measuring only 1 m (3 ft 3 in) long. However, they are not vestigial but instead show large areas for muscle attachment, indicating considerable strength. This was recognized as early as 1906 by Osborn, who speculated that the forelimbs may have been used to grasp a mate during copulation.[38] It has also been suggested that the forelimbs were used to assist the animal in rising from a prone position.[34] Another possibility is that the forelimbs held struggling prey while it was dispatched by the tyrannosaur's enormous jaws. This hypothesis may be supported by biomechanical analysis. T. rex forelimb bones exhibit extremely thick cortical bone, indicating that they were developed to withstand heavy loads. The biceps brachii muscle of a full-grown Tyrannosaurus rex was capable of lifting 199 kg (438 lb) by itself; this number would only increase with other muscles (like the brachialis) acting in concert with the biceps. A T. rex forearm also had a reduced range of motion, with the shoulder and elbow joints allowing only 40 and 45 degrees of motion, respectively. In contrast, the same two joints in Deinonychus allow up to 88 and 130 degrees of motion, respectively, while a human arm can rotate 360 degrees at the shoulder and move through 165 degrees at the elbow. The heavy build of the arm bones, extreme strength of the muscles, and limited range of motion may indicate a system designed to hold fast despite the stresses of a struggling prey animal.[39]
[ Feathers
In 2004, the scientific journal Nature published a report describing an early tyrannosauroid, Dilong paradoxus, from the famous Yixian Formation of China. As with many other theropods discovered in the Yixian, the fossil skeleton was preserved with a coat of filamentous structures which are commonly recognized as the precursors of feathers. It has also been proposed that Tyrannosaurus and other closely-related tyrannosaurids had such protofeathers. However, rare skin impressions from adult tyrannosaurids in Canada and Mongolia show pebbly scales typical of other dinosaurs. While it is possible that protofeathers existed on parts of the body which have not been preserved, a lack of body covering is consistent with modern multi-ton animals such as elephants, hippopotamus, and most species of rhinoceros, all of which lack hair over most of their bodies. As animals increase in size, their ability to retain heat increases due to their decreasing surface area-to-volume ratios. Therefore, as large animals evolve in or disperse into warm climates, a coat of fur or feathers loses its selective advantage for thermal insulation and can instead become a disadvantage, as the insulation traps excess heat inside the body, possibly overheating the animal. Protofeathers may also have been secondarily lost during the evolution of large tyrannosaurids like Tyrannosaurus, especially in warm Cretaceous climates.[40] Some scientists speculate that young tyrannosaurs may have had a feathery down, similar to modern bird chicks, but this is purely guesswork.
[ Tyrannosaurus warm-blooded?
Main article: Warm-bloodedness of dinosaurs
Tyrannosaurus has been at the centre of the warm-blooded versus cold-blooded debate ever since its beginnings with the paleontologist Robert T. Bakker. Like many other theropods, Tyrannosaurus is thought to have been warm-blooded due to its heightened levels of activity. To have been able to capture prey actively for example, it would have been useful to the creature to be warm-blooded. T. rex also has anatomical features distinctly similar to birds, which are warm-blooded. However, since the birth of the theory that Tyrannosaurus was in fact a scavenger, the theory that Tyrannosaurus was warm-blooded has been cast into doubt. Although Bakker provided some important factual evidence, paleontologists are still divided on the issue.[41][42]
[ Feeding strategies

Most debate about Tyrannosaurus centers on its feeding patterns and locomotion. One paleontologist, noted hadrosaur expert Jack Horner, claims that Tyrannosaurus was exclusively a scavenger and did not engage in active hunting at all.[37] Horner has only presented this in an official scientific context once, while mainly discussing it in his books and in the media. His hypothesis is based on the following: Tyrannosaurs have large olfactory bulbs and olfactory nerves (relative to their brain size). These suggest a highly developed sense of smell, allegedly used to sniff out carcasses over great distances. Tyrannosaur teeth could crush bone, a skill perhaps used to extract as much food (bone marrow) as possible from carcass remnants, usually the least nutritious parts. Since at least some of Tyrannosaurus's prey could move quickly, evidence that it walked instead of ran could indicate that it was a scavenger.[43][44]
Most scientists who have published on the subject since insist that Tyrannosaurus was both a predator and a scavenger, taking whatever meat it could acquire depending on the opportunity that was presented.[45] Modern carnivores such as lions and hyenas will often scavenge what other predators have killed, suggesting that tyrannosaurs may also have done so.[46]
Some other evidence exists that suggests hunting behavior in Tyrannosaurus. The ocular cavities of tyrannosaurs are positioned so that the eyes would point forward, giving the dinosaur binocular vision.[47] A scavenger might not need the advanced depth perception that stereoscopic vision affords; in modern animals, binocular vision is found primarily in predators.
When examining Sue, paleontologist Pete Larson found a broken and healed fibula and tail vertebrae, scarred facial bones and a tooth from another Tyrannosaurus embedded in a neck vertebra. If correct, it might be strong evidence for aggressive behavior between tyrannosaurs but whether it would be competition for food and mates or active cannibalism is unclear.[48] However, further recent investigation of these purported wounds has shown that most are infections rather than injuries (or simply damage to the fossil after death) and the few injuries are too general to be indicative of intraspecific conflict.[49] In the Sue excavation site, an Edmontosaurus annectens skeleton was also found with healed tyrannosaur-inflicted scars on its tail. The fact that the scars seem to have healed suggests active predation instead of scavenging a previous kill.[50][51] Another piece of evidence is a Triceratops found with bite marks on its ilium. Again, these were inflicted by a tyrannosaur and they too appear healed.[52]
There have been conflicting studies regarding the extent to which Tyrannosaurus could run and exactly how fast it might have been; speculation has suggested speeds up to 70 km/h (45 mph) or even more. However, according to James Farlow, a palaeontologist at Indiana-Purdue University in Fort Wayne, Indiana, "If T. rex had been moving fast and tripped, it would have died."[53] If it tripped and fell while running, a tumbling tyrannosaur's torso would have slammed into the ground at a deceleration of 6g (six times the acceleration due to gravity, or about 60 m/s²).[5] (See also Locomotion, below.)
Some argue that if Tyrannosaurus were a scavenger, another dinosaur had to be the top predator in the Amerasian Upper Cretaceous. Top prey were the larger marginocephalians and ornithopods. The other tyrannosaurids share so many characteristics that only small dromaeosaurs remain as feasible top predators. In this light, scavenger hypothesis adherents have suggested that the size and power of tyrannosaurs allowed them to steal kills from smaller predators.[44]
[Locomotion

Scientists who think that Tyrannosaurus was able to run slowly point out that hollow Tyrannosaur bones and other features that would have lightened its body may have kept adult weight to a mere 5 tons or so, or that other animals like ostriches and horses with long, flexible legs are able to achieve high speeds through slower but longer strides. Additionally, some have argued that Tyrannosaurus had relatively larger leg muscles than any animal alive today, which could have enabled fast running (40–70 km/h or 25–45 mph).[54]
Some old studies of leg anatomy and living animals suggested that Tyrannosaurus could not run at all and merely walked. The ratio of femur (thigh bone) to tibia (shank bone) length (greater than 1, as in most large theropods) could indicate that Tyrannosaurus was a specialized walker, like a modern elephant. In addition, it had tiny 'arms' that could not have stopped the dinosaur's fall, had it stumbled while running; standard estimates of Tyrannosaurus weight at 6 to 8 tons would produce a lethal impact force, should it have fallen.[55] It should be noted, however, that giraffes have been known to gallop at 50 km/h (31 mph).[56] At those speeds, the animal risks breaking a leg or worse, which can be fatal even when the accident occurs in a 'safe' environment, such as a zoo.[57] If it could run, Tyrannosaurus may have been a risk-taker, in much the same way as animals alive today are. Yet estimates of leg bone strength in Tyrannosaurus show that its legs were little, if any stronger, than those of elephants, which are relatively limited in their top speed and do not ever become 'airborne', as would happen in running.
Walking proponents estimate the top speed of Tyrannosaurus at about 17 km/h (11 mph). This is still faster than the most likely prey species that co-existed with tyrannosaurs; the hadrosaurs and ceratopsians.[58] In addition, some predation advocates claim that tyrannosaur running speed is not important, since it may have been slow but better designed for speed than its probable prey[59] or it may have used ambush tactics to attack faster prey animals.[54]


The most recent research on Tyrannosaurus locomotion does not specify how fast Tyrannosaurus may have run, but admits that there is little capacity to narrow down speeds further than a range from 17 km/h (11 mph), which would be only walking or slow running, to 40 km/h (25 mph), which would be moderate-speed running. For example, a paper in Nature[58] used a mathematical model (validated by applying it to two living animals, alligators and chickens) to gauge the leg muscle mass needed for fast running (over 25 mph / 40 km/h). They found that proposed top speeds in excess of 40 km/h (25 mph) were unfeasible, because they would require very large leg muscles (more than approximately 40–86% of total body mass.)[60] Even moderately fast speeds would have required large leg muscles. This discussion is difficult to resolve, as it is unknown how large the leg muscles were. If they were smaller, only ~11 mph (18 km/h) walking/jogging might have been possible.[54]
