The Geological Column Continued?

Question

With the geo column stating that dinosaurs found in layers of rock dating so and so millions of years the question is:
Why is it sooo much easier to find dinosaurs that have been dead for at least 65 million years, than cro-magnum and any other form of man that havfe been dead for only 3 million years.
Cro-magnum, erectus, and habilius should be the frisdt things we encounter when we dig, instead it's easier to find dinos extinct for said millions of years in a column which indicates our ancient man cousins should be arrvinig first.
If anyone goes on about the difficulty of fossilisation after 3 million years, bear in mind they have found fossilised hats, hammers and cowboy boots, with fossilised cowboy feet inside them.
Further, if extinction and evo depend on changes to habitat, and some creatures have survived such as the caelocanth as its habitat is unchaged, then why did cro-mags, erectus, and habilius man dissapear?They lived in caves and jungles, which we still have today

Answer 1

Your question requires a more fulsome answer; but in brief it is this:

fossils are generally created by the impact of disaster i.e: - burial by floods, in tar pits and death occuring in areas where predation is difficult - such as caves (too whit - Cheddar man in the UK) .. however in most cases there are few fossils - such as human or near relatives due to death occurring in non buried areas and therefore subject to destruction by predators .. note that since the inception of burials etc., that human remains are found in considerable numbers .. also be aware that petrification and fossilisation are somewhat different .. study the remains at Pompeii where some are fossilised and some are petrified .. in Australia we have fossilized wood and petrified wood.. fossilized is caused by injection of silicates (Opal) and petrification is caused by 'preservation' by other means such as mud and continual immersion in water .. and of course predation can be from such creatures as scavengers and/or bacteria, moulds etc.,

Answer 2

You need to pick up the most basic geology book. There is not an unbroken stratigraphic record under your feet. Tectonic movements, erosion and non-deposition at many times in the geological past have seen to that. Geologists aren't stupid.

Secondly, you need honest logic. Dinosaurs were around for 160 million years and dominated ecoystems around the world with around 2000 genera. In contrast the one Homo genus you refer to has been around for around for only ~2 million years, mostly in Africa.

Thirdly, you need honest 'facts'. Extinction and evolution DOESN'T just depend on habitat, but on the whole ecosystem, including competition, as well as more random things. The vast vast majority of species to ever exist are now extinct, including the species of Coelacanth (Order) known from fossils. The 2 species of Coelacanth allive today (in deep marine environments that leave little fossil record on land) are not the same species, or even the same genus as the fossil ones.

Answer 3

Fossilisation is a rare process. Most animals die without trace. Dinosaurs were around for over 200 million years, hominids for about 3 million. You are going to find a lot more fossils of dinosaurs than hominids just because of the time period involved.

Many fossils of dinosaurs have been found and many fossils of mammals have been found. There were thousands of species of dinosaur just as there have been thousands of species of mammals. The number of dinosaur fossils is a tiny percentage of those that lived. If you restrict the fossils to particular species, say T rex, then the number of fossils is a mere handful the same as particular species of mammal. You have to compare like with like.

The number of hominid fossils is small compared with the number of mammal fossils which is what you would expect. For the same reasons they are small compared with the number of dinosaur fossils.
