User:A Cynical Idealist/Project Coelurosauria

From Wikipedia, the free encyclopedia
Six exemplar coelurosaurs (clockwise from top left): Tyrannosaurus rex, Sinosauropteryx prima, Deinonychus antirrhopus, Archaeopteryx lithographica, the Zamyn Khondt oviraptorid, and Passer domesticus

This is my comprehensive attempt to improve Wikipedia's coverage of coelurosaurs, their evolution, and their taxonomy.

Coelurosaurs are one of the most successful groups of animals in Earth's history, and they include the birds, which are the most diverse group of terrestrial vertebrates alive today. They are also among the most well-sampled and studied of all prehistoric animals. My goal is to expand coverage of the lesser-known coelurosaurs because many of them feature prominently in the scientific literature, but this is not reflected on Wikipedia.

Taxon merges

My format for expanding a page for a taxon follows the guidelines of WP:DINO and WP:PAL, which suggest the following format for structuring an article:

  • Intro paragraph including etymology and a brief summary
  • Discovery
  • Description: size estimates, any species, skull, post-cranial anatomy
  • Classification: phylogeny, evolution, possible synonymity
  • Paleobiology: pathology, reproduction, ontogeny, behavior
  • Paleoecology: range, diet, predators, paleoenvironment, contemporary fauna
