Dinosaur eggs vary greatly in size and shape, but even the largest dinosaur eggs (Megaloolithus) are smaller than the largest known bird eggs, which were laid by the extinct elephant bird. Dinosaur eggs range in shape from spherical to highly elongated (some specimens three times longer than they are wide).
Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists. Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds , which can weigh as little as two grams, to the extinct titanosaurs , such as Argentinosaurus and ...
The specimen's considerable size places it within the range of known T. rex individuals, suggesting the presence of large tyrannosaurids during the Campanian stage (~75 million years ago), a temporal range earlier than the established Maastrichtian age (~68–66 Ma) for Tyrannosaurus rex. However, the exact age and provenance of CM 9401 remain ...
A discovery of features in a Tyrannosaurus rex skeleton provided more evidence that dinosaurs and birds evolved from a common ancestor and, for the first time, allowed paleontologists to establish the sex of a dinosaur. When laying eggs, female birds grow a special type of bone between the hard outer bone and the marrow of their limbs.
The dinosaur's bones were discovered in a mine in Wales in the 1950s. A more recent analysis found that the ignored fossils are a distinct species.
