Macrodontopteryx is a Pseudotoothed bird from the London Clay Formation of England, distinct from yesterday’s Dasornis, though originally it was thought to be a member of that genus. It lived about 55 to 50 million years ago, in the Ypresian age of the Eocene of the Paleogene. It is known from a crushed skull with most of the beak missing, so it’s difficult to say much about the genus, though it probably would have had a wingspan of about 4 meters in length, making it fairly average in size. It may have other remains from as late as the Oligocene as well.

Name: Proceriavis martini

Status: Extinct

First Described: 1979

Described By: Harrison and Walker

Classification: Dinosauria, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Averaptora, Avialae, Euavialae, Avebrevicauda, Pygostylia, Ornithothoraces, Euornithes, Ornithuromorpha, Ornithurae, Neornithes

Proceriavis is a poorly known bird from the Isle of Wight in England, living about 32 million years ago, in the Rupelian of the Oligocene of the Paleogene. It is only known from fragments of a vertebra and part of the foot, though it does seem to be similar to modern ratites such as the Cassowary, so that might be what kind of bird it is.
