Recently finished my latest reconstruction of the large flightless bird Gastornis gigantea. The fossil remains of these birds have been found in western-central Europe (England, Belgium, France and Germany).More complete specimens are known from a fourth, North American species, which had previously been classified in the distinct genus Diatryma.

"Giant ground birds at the Cretaceous-Tertiary boundary: Extinction or survival?"
Gaston’s Giant Bird (Gastornis gigantea) was a large, flightless bird that inhabited North America during the early Eocene.
"Reappraisal of the bone inventory of Hou, L. (1980) New form of the Gastornithidae from the Lower Eocene of the Xichuan, Honan. Gastornis had large powerful legs, with large, taloned feet, which also were considered in support of the theory that it was a predator. Some fibrous strands recovered from a Green River Formation deposit at
The genus is currently thought to contain three or four distinct species
Gastornis parisiensiksen korkeus oli keskimäärin 1,75 metriä, mutta suurin laji, G. gigantea, kasvoi jopa kaksimetrisiksi. "The skeleton of Buffetaut, E., and Burrrraur, E. (1997). Hellmund, M. (2013). Geological Museum Department of Geology and Geophysics Diatryma gigantea 'Giant Bird' Geologic Time: 55 million years ago (Early Eocene) Geographic Range: Wyoming, New Mexico, Colorado, New Jersey, Canada's Ellesmere Island, France, Germany Adult Size: Total Height - 7 ft. (2.14 m); Skull Length - 1.5 ft. (0.5 m); Weight - 385 lbs. Gastornis parisiensis measured on average 1.75 metres tall, but large individuals grew up to 2 metres tall. Diatryma gigantea was considered the best speciment from this group.
Naturwissenschaften (advance online publication) DOI: 10.1007/s00114-014-1158-2 That is why the mission of this project is to be a guide to the world of prehistoric fauna - undiscovered and incredibly beautiful. It was found in late Eocene The problem with these early trace fossils is that no fossil of Matthew, W.D., Granger, W., and Stein, W. (1917). Andors, A.V. Designed by you may use several options to pay for the image, such as credit cards (Visa, MasterCard and Maestro) or Bank transfer (wire transfer) Gastornis are herbivores which will seek out and eat ancient ferns, flowers, grass, and leaves.
Recognizing the apparent close relationship between gastornithids and waterfowl, some researchers classify gastornithids within the anseriform group itself.A simplified version of the family tree found by Agnolin Some of these fragments were complete enough to reconstruct a size of 24 by 10 cm (about 9.5 by 4 inches) with shells 2.3–2.5 mm (0.09–0.1 in) thick,Several sets of fossil footprints are suspected to belong to Another footprint record consists of a single imprint that still exists, though it has proven to be even more controversial. Gastornis is an extinct genus of large flightless birds that lived during the late Paleocene and Eocene epochs of the Cenozoic era. The plumage of Gastornis is unknown; it is generally depicted with a hair-like covering as in ratites, but this is conjectural. A Gastornis gigantea (2 m) enjoying some palm nuts while also mingling with and inadvertently providing protection for a herd of miniature horses, Eohippus angustidens, from the carnivorous ungulate Mesonyx nuhetingensis, Wyoming, 50 million years ago.. Gastornis, a distant flightless relative of ducks, geese and swans, was one of Earth’s earliest megafauna to emerge in the …
Gastornis is an extinct genus of large flightless bird that lived during the late Paleocene and Eocene epochs of the Cenozoic. Gastornis species were very large birds, and have traditionally been considered to be predators of small mammals.
Implications for the structure of Paleocene terrestrial ecosystems. Gastornis is a species of large flightless bird that lived during the early Cenozoic era. It’s even bigger than a Velociraptor, its not-so-distant relative.But while it might have looked frightening, scientists now think this extinct bird was actually a vegetarian related to ducks and geese. The genus is currently thought to contain three or four distinct species, known from incomplete fossil remains, found in western … "Reappraisal of the Eocene ground bird Buffetaut, E. (2002). It was originally considered separate from the Genus Gastornis, which resided in Europe, but taxonomists decided the evidence indicated Gastornis and Diatryma were the same genus and Diatryma was folded into Genus Gastornis.
"New remains of the giant bird Martin, L.D. Its fossils have been found mostly in Western Europe and also in North America, where it was previously known as Diatryma.
