Fish, reptiles, birds, and naming of dinosaurs Richard Owen in 1856 with the skull of a crocodile Owen's coining of the word dinosaur in 1841 Most of his work on reptiles related to the skeletons of extinct forms and his chief memoirs, on British specimens, were reprinted in a connected series in his History of British Fossil Reptiles (4 vols ...
The idea that dinosaurs were similar to birds was first proposed by Thomas Henry Huxley in the 1860s, but was dismissed by Gerhard Heilmann in his influential book The Origin of Birds (1926). [ 7 ] [ 8 ] [ 9 ] Prior to Ostrom's work, the development of birds was generally believed to have split off early on from that of dinosaurs.
The trend continued in the 20th century with additional regions of the Earth being opened to systematic fossil collection. Fossils found in China near the end of the 20th century have been particularly important as they have provided new information about the earliest evolution of animals, early fish, dinosaurs and the evolution of birds.

A turning point came in the early twentieth century with the writings of Gerhard Heilmann of Denmark.An artist by trade, Heilmann had a scholarly interest in birds and from 1913 to 1916, expanding on earlier work by Othenio Abel, [12] published the results of his research in several parts, dealing with the anatomy, embryology, behavior, paleontology, and evolution of birds.

Ancestral birds like Archaeopteryx [1] first evolved from dinosaurs during the Jurassic, with crown-group birds emerging in the Cretaceous between 100 Ma and 60 Ma. [ 2 ] The K-Pg mass extinction wiped out many vertebrate clades, including the pterosaurs , plesiosaurs , mosasaurs and nearly all dinosaurs , leaving many ecological niches open.
Based on fossils from 1,000 dinosaur species and paleoclimate information, the new study looked at the spread of dinosaurs across different environments on Earth throughout the dinosaur era, which ...
Researchers unearthed the skull of a previously unknown starling-sized bird species named Navaornis hestiae that was so well preserved they were able to digitally reconstruct its brain and inner ...
Palaeozoology, also spelled as Paleozoology (Greek: παλαιόν, palaeon "old" and ζῷον, zoon "animal"), is the branch of paleontology, paleobiology, or zoology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
