New Study Sheds glow- Dinosaur Size

Dinosaurs were not only the biggest animals to wander the Earth -- they also had a better number of bigger species compared to all other back-boned animals.

The researchers, from Queen Mary, University of London, compared the dimension of the femur bone of 329 dissimilar dinosaur species from fossil records. The length and weight of the femur bone is a documented method in paleontology for estimating a dinosaur's body mass.

They found that dinosaurs pursue the reverse model of body size distribution as seen in other vertebrate species. For example, within living mammals there tends to be little better species, such as elephants, compared to lesser animals, such as mice, which have many species. The proof from fossil records implies that in difference there were many species of better dinosaurs and few small species.

Our proof supports the hypothesis that youthful dinosaurs busy a dissimilar environmental place to their parents so they weren't in competition for the similar sources of food as they ate smaller plants or preyed on lesser size animals. In fact, we see modern crocodiles following this model baby crocodiles begin by feeding off insects and tadpoles before graduating on to fish and then bigger mammals.
