Scientists have discovered remnants of a strange dinosaur with an unusual combination of traits in southern Chile. It was named Chilesaurus diegosuarezi to honor the country where it was unearthed and the 7-year-old who spotted the first fossils. "The skeletal anatomy of Chilesaurus gathers characteristics of different dinosaur groups, like a floor is composed of mosaics of different shapes and colors. No other dinosaurs exhibit such a combination or mixture of features," said paleontologist Fernando Novas of the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires. The modern-day version of such misfit is the platypus, an egg-laying, duck-billed mammal from Australia, Reuters reported on 27 April 2015.
Chilesaurus it is a member of the same dinosaur species as Tyrannosaurus rex. Its skull and neck bear a resemblance to those of primeval long-necked dinosaurs, and its vertebrae those of primitive meat-eating theropods which are the largest land meat-eaters in Earth's history. Strangely enough Chilesaurus ate only plants, given a beak and leaf-shaped teeth and two blunt fingers on each hand. It is a two-legged created with a bird-like pelvis. Unlike the three-talon feet of most theropods, Chilesaurus had a wide feet with four toes. Four nearly complete skeletons frames were found to establish these typical misfit traits. It was relatively small, reaching up to 10.5 feet (3.2 meters) long, although most specimens found were more the size of a turkey. It lived in a region crisscrossed by rivers approximately 145 million years ago.
University of Birmingham paleontologist MartÃn Ezcurra said, "The most interesting (aspect) about Chilesaurus is the story that it tells about how evolution works, 'Convergent evolution' is a process in which two unrelated species or groups acquire similar characteristics from living in similar environments or having a similar behavior," He used the example of having the wings of a bat and a bird. For 'mosaic convergent evolution,' it involves different parts of the body resembling those of other unrelated species.
My Comments
The more fossil we unearth, the harder it would be for experts to explain evolution. Very soon the theory of evolution will just fall apart. It would be easier to explain explain that the Chilesaurus came from a big bang than to fit it into evolution theory. After we finally believe the earth cam from a big bang.
