Simple, branched, feather-like structures are known from heterodontosaurids, primitive neornithischians [137] and theropods, [138] and primitive ceratopsians. Ammonites constantly built new shell as they grew, but only lived in the outer chamber. This speciation is not “evolution,” since it is based on the created information already present and is thus a limited, downhill process, not involving an upward increase in complexity. While some later pterosaurs could be absolutely massive, reaching the size of a small plane, this first pterodactyloid pterosaur only had a wingspan of about 1.4 meters (4.5 ft).

But the average size of a dinosaur, based on the skeletons found over the earth, is about the size of a large sheep or bison. 38 Indeed, many dinosaurs were relatively small. The long neck, in turn, could only evolve because of the small head and the extensive pneumatization of the sauropod axial skeleton, lightening the neck. Rebuilding a complete skeleton by comparing the size and morphology of bones to those of similar, better-known species is an inexact art, and reconstructing the muscles and other organs of the living animal is, at best, a process of educated guesswork. [69] The tallest and heaviest dinosaur known from good skeletons is Giraffatitan brancai (previously classified as a species of Brachiosaurus ).

Shark teeth that are normally 3/4" across, have been found as big as two foot across. Alternatively the bones may completely decay leaving a cast of the organism. If the bone is not buried or underwater within 1-2 years of defleshing, it will literally become dust in the wind. Payment accepted in UK Pounds, EURO, AUD and US Dollars. Hawkins, pictured standing under the skeleton, mocked up a giant iguana skull, and painted it green for this display.)

This destroyed the habitat of the animals living in those forests. The natives identified a picture in a kid's coloring book of a diplodocus as Mokele Mbembe. This line of reasoning should make us wonder if there is other evidence indicating that during the Mesozoic era that the world was a dramatically different place.

There is also physical evidence that dinosaur bones are not millions of years old. The activities and discussions of this lesson revolve around comparing and contrasting dinosaurs to animals with which students are familiar. See new additions including the 228- million- year- old Eoraptor, the bird-like Bambiraptor, and the amazing Jobaria - a 22-metre- long sauropod (long-necked plant- eater) rearing to a whopping 10 metres!
