	Gastornis - Wikipedia, the free encyclopedia
		Gastornis is an extinct genus of large flightless birds that lived during the late Paleocene and Eocene periods of the Cenozoic.
		Gastornis lived in Europe, but it had an extremely close relative in North America; the North American bird is often called Diatryma, but experts now believe they both belong in the Gastornis genus.
		It had a remarkably huge beak, which may mean that it was carnivorous (although the beak may simply have been used for sexual display and probably was better suited for crushing than for tearing or cutting action).

	InfoHub - Gastornis
		Gastornis pariensis was a bird species that lived in the late Paleocene and early Eocene.
		Gastornis is so similar to Diatryma that some scientists think the two may be one and the same.
		Whether Gastornis and Diatryma turn out to be congeneric or not, the stratigraphic record of gasornithids, if it accurately reflects the temporal distribution of these birds in Europe and North America, may have some interesting implications for their biogeographical history.

		The first episode depicts the warm tropical world of the early Eocene which was 16 million years after the extinction of the dinosaurs.
		While the family is foraging, a female Gastornis successfully hunts down a Propalaeotherium and defends her territory from another Gastornis.
		Unfortunately, while the Gastornis is out hunting, a horde of large ants (known as Formicium) ambush its baby.

	BBC - Science & Nature - Wildfacts - Gastornis
		Gastornis lived on the forest floor in the great expanses of rainforest which covered the land in the Eocene.
		Gastornis was one of the largest animals around at the time, and because of its size and heavy build it can't have been a fast runner.
		Diatryma is a name often used for Gastornis, and is the name given to it in the US.

	ISGS Gastornis
		Answer: Gastornis would have needed quite a lot of food to keep such a big body well fed, so they would have been spread out sparsely in the forest and were likely to have had to protect their home range against other Gastornis.
		The carnivorous Gastornis would be more likely to have very few eggs, with the chick needing to be well formed so as to be able to escape predators on the ground as soon as possible.
		Gastornis was probably an ambush hunter, so it may have needed slightly drabber colours - at least on its underside and legs, which is possibly the last thing its prey would ever have seen!

	ABC - Science - Beasts - Gastornis Factfile
		Gastornis fossils are common at the Geiseltal site in Germany, and in the USA.
		Gastornis was one of the largest animals around at the time.
		Given its huge size, Gastornis must have been a silent ambush hunter in the thick forests.

	BBC News \| SCI/TECH \| When birds ate horses
		The fossil was found at the Messel open-pit mine in Germany, where more than 70 specimens of ancient horses have now been unearthed.
		The forest dwelling horses come from a time, 49 million years ago, when tropical forests stretched right to the poles.
		The largest mammals were about the size of a pig, and giant stalking birds, Gastornis, took the role of top predators.

	ABC - Science - Beasts - Evidence - Programme 1 - Gastornis
		With huge stalking birds like Gastornis as top predators of the Eocene forests you could say that dinosaurs were still ruling the world.
		A German site called Geiseltal contains several skeletons, and in fact the same bird also lived right across North America, so there is plenty of evidence to help us build it.
		The only issue is whether Gastornis used its huge beak for cracking nuts, or bones.

	Croydon Natural History and Scientific Society - Archives (Site not responding. Last check: 2007-09-10)
		The site is important for the discovery there, during 1883 when the Woodside and South Croydon Railway was being made, of several fossils new to science, including Gastornis klaasseni (a gigantic bird) and Coryphodon croydonensis (a mammal).
		What is even more interesting is that etching on the surfaces of the teeth of the Croydon specimen indicates that it had been eaten and digested by an even larger predator.
		A possible candidate for this is the giant flightless bird, Gastornis klaasseni, whose bones were found at exactly the same site in Sandilands cutting in 1883.

	Paleocene mammals of the world
		However, they are entirely unknown from the rich fossil record of the North American Paleocene: The famous Diatryma first appears there in the early Eocene.
		Although the mesonychid Pachyaena is known from the latest Paleocene, this encounter must be placed in the early Eocene when Diatryma first appears.
		Smaller mesonychids of the genus Dissacus occur together with the large flightless bird Gastornis in the Paleocene of Europe.

	Optics Blog - binocualrs telescopes birdwatching astronomy scopes: Gastornis in my backyard
		Got a summer cold over the weekend, so had to settle for using the Nikon on yard birds.
		With the Nikon, I could count not just individual feathers, but individual feather parts on each feather.
		The males beak reminded me of pictures I have seen of the prehistoric giant bird, Gastornis.

		Possible new taxon of penguin is abundant at the site - might be the same thing as the very numerous but underdescribed Pisco Fm.
		Eric Buffetaut: Gastonis and Diatryma are congeneric (meaning that the latter must be sunk) and both 'genera' already had overlapping stratigraphic and geographical ranges (though Gastornis has not been reported from outside of Europe, Diatryma has long been regarded as a denizen of Eocene France and Germany).
		Means that Gastornis now extends from the late Palaeocene to the late Eocene.

		Speaking of them, Gastornis and Diatryma are the same right?
		I've never heard of the first two, and the last one, I think, is an error perpetrated by the toy industry.
		Gastornis (Europe) and Diatryma (South America) have different type species, but some researchers feel they are similar enough to include under one genus (Gastornis).
