No. Birds are found in the fossil record intact with feathers and all. The feather structures of birds are very complicated with hollow bones that are trussed for light weight and strength. The idea that because some dinos walked on two legs means that birds must have come from them is false reasoning. You might as well believe that man also came from dinos because he is bipedal also. A birds heart in general is made to beat at great beats per minutes unlike a reptile because of the great wing activity that uses up a lot of energy. Some genetics researchers try to get us to believe that there are similarities in bird and dinosaur genes that proves common descent. Wrong. Similarity is not enough proof of common descent. A watermelon, a cloud and a human all have about 75% water but they have no common descent.

According to the most modern classification scheme I have seen, it has been decided that dinosaurs are indeed reptiles. It has been known for some time that birds are dinosaurs - they are related to coleurosaurs and sauropods in general, especially tyrannosaurus rex, which may have had feathers. Therefore, birds are reptiles.
A common characteristic among almost all reptiles, then (except a few snakes) is that they lay eggs, while a common characteristic among mammals (except the platypus) is that they bear young alive. Reptiles can be either cold-blooded or warm-blooded, while all mammals are warm-blooded.
There have been two main groups of advanced major life on the Earth, then: reptiles and mammals.

Coincidence? I don't think so!
Summer Dinosaur
1 1/2 pounds dinosaur meat, trimmed from the bone
water
2 stalks celery
1 clove garlic
1/4 cup olive oil
1/4 cup lemon juice
1/4 to 1/2 cup chopped scallions
Put dinosaur parts and celery (cut up) in a pot and cover with water. Bring to a hard boil for 5 minutes then cover the pot tightly and remove from heat. Do not touch or uncover until completely cool - VERY completely cooled. Skin dinosaur and break into small pieces (save stock for soup, etc..). Mix the dinosaur pieces with the remaining ingredients. Serve cold.

There is no question that birds are theropod dinosaurs, but they have evolved so far away from their dinosaur ancestors that most of us think of them as "birds" which is not identically the same as "dinosaurs". Mammals are evolved from synapsid reptiles, but they too have evolved so much since the days of reptiles that it is kind of silly to call birds dinosaurs and mammals synapsid reptiles. All of these are evolved from Coelecanthe fish so why not call all land vertebrates "fish"? or maybe since the fish as well as the insects and most other animal life originally evolved from multi-segmented worms, we could call everyone a worm?And these all evolved from jellyfish, who evolved from amoebas, who evolved from bacteria..........maybe we are all just bacteria?

They are closely related to dinosaurs but aren't' technically in the family Dinosauria.

Mmmm where can I get some of that dino soup?
by the way, bacteria evovled separately from us, they are prokaryotic while we are eukaryotic, so we couldnt have elvolved from bacteria
