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.
These cats were traceable as descendants of the discontinued Dutch Rex breeding program. The last known Dutch Rex was a female cat of unknown origin found in Amsterdam in the late 1990s. The dominant mutation produced a rex type of coat in the heterozygote and a sparse coat in the homozygote. 1972: Victoria Rex.
The red junglefowl was the primary species to give rise to today's many breeds of domesticated chicken (G. g. domesticus); additionally, the related grey junglefowl (G. sonneratii), Sri Lankan junglefowl (G. lafayettii) and the Javanese green junglefowl (G. varius) have also contributed genetic material to the gene pool of the modern chicken ...
Speaking of descendants, there are some animals that we consider the descendants of dinosaurs that may surprise you. Like chickens: velociraptors and the T-Rex are actually ancestors of birds ...
At present, two species of Tyrannosaurus are considered valid; the type species, T. rex, and the earlier in age and more recently discovered T. mcraeensis. As the archetypal theropod, Tyrannosaurus has been one of the best-known dinosaurs since the early 20th century and has been featured in film, advertising, postal stamps, and many other media.
Many presentations still describe Compsognathus as "chicken-sized" dinosaurs because of the size of the German specimen, which is now believed to be a juvenile. Compsognathus longipes is one of the few dinosaur species whose diet is known with certainty: the remains of small, agile lizards are preserved in the bellies of both specimens. Teeth ...
This clade was defined by Sereno (1999) as "Tyrannosaurus rex, Passer domesticus (the house sparrow), their last common ancestor, and all of its descendants". [18] As tyrannosauroids are considered to be the most basal large group within Coelurosauria, this means that the common ancestor of tyrannosauroids and birds was an even more basal ...
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.
