Ebrachosuchus
Encyclopedia
Ebrachosuchus is an extinct genus
of basal
phytosaurid phytosaur
. Fossil
s were first discovered from the Blasensandstein Formation near Ebrach
, Germany
, which dates back to the Carnian
stage of the Late Triassic
.
The original holotype
of E. neukami had a very elongate rostrum
that was used to distinguish the genus from other phytosaurs. However, due to its many other similarities to the closely related Paleorhinus
, Ebrachosuchus has since been considered to be synonymous
with Paleorhinus. The rostrum length alone would not be enough to assign the original specimen of E. neukami to its own genus or subgenus, according to the authors of one paper proposing the synonymy.
Genus
In biology, a genus is a low-level taxonomic rank used in the biological classification of living and fossil organisms, which is an example of definition by genus and differentia...

Basal (phylogenetics)
In phylogenetics, a basal clade is the earliest clade to branch in a larger clade; it appears at the base of a cladogram.A basal group forms an outgroup to the rest of the clade, such as in the following example:...

Phytosaur
Phytosaurs are an extinct group of large semi-aquatic Late Triassic archosaurs. Phytosaurs belong to the family Phytosauridae and the order Phytosauria. They were long-snouted and heavily armoured, bearing a remarkable resemblance to modern crocodiles in size, appearance, and lifestyle, an example...

The Late Triassic is in the geologic timescale the third and final of three epochs of the Triassic period. The corresponding series is known as the Upper Triassic. In the past it was sometimes called the Keuper, after a German lithostratigraphic group that has a roughly corresponding age...

A holotype is a single physical example of an organism, known to have been used when the species was formally described. It is either the single such physical example or one of several such, but explicitly designated as the holotype...

Paleorhinus
Paleorhinus was a genus of small phytosaur, a large order of semi-aquatic, crocodile-like animals that lived in the Late Triassic, specifically the earlier Late Carnian period. The reptiles lived throughout Europe, North America, and North Africa. This genus usually also includes the more...

In scientific nomenclature, a synonym is a scientific name that is or was used for a taxon of organisms that also goes by a different scientific name. For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies...
