The paper referred only Stratiotosuchus maxhechti and Baurusuchus to the subfamily, making Stratiotosuchus Baurusuchus’ closest relative so far. Papeis Avulsos de Zoologia. Vasconcellos 1Thiago S. Alberto Barbosa de Carvalho, Brazilian paleontologist. The postcranial skeleton of B. Related categories Terrestrial crocodylomorphs.
Baurusuchus likely played an important role in its ecosystem, competing with the abelisaurids for food. The imbrication of dorsal armor assists the limb-driven locomotion of many crocodyliform by reducing the flexibility of the dorsal spine during the high-walk erect stance.
The occurrence of very complete skeletons in correlated stratigraphic levels supports this. Permission Reusing this file. The strongly bent pterygoids suggest a powerful bite and that Baurusuchus could close its jaw very quickly. The appendicular bones of B. The dorsal vertebrae are close articulated with short and craniocaudally expanded neural spines, specially the posterior ones. Views View Edit History.
The close articulation of the dorsal vertebrae may indicate a less flexible dorsal spine, ideal to limb-driven methods of locomotion. The medial portion has little variation along the scutes rows and may bear medial lamellar dorsoventral structures of articulation to the adjacent bony plate. Therefore the long and stout limb bones, overhanging crest of the illium and the light weighted armor, also allowed to B.

The only morphological difference appears at the caudalmost portion of the tail, where the osteoderms are craniocaudally elongated. The skull and tooth morphology indicates that the biting strategies of Baurusuchus were similar to a Komodo dragon which include ambushing bautusuchus prey, biting it and pulling back the serrated, blade-like teeth. Baurusuchus is the type genus of the family Baurusuchidaea family consisting of crocodilians with elongated and laterally compressed skulls.
The hot environment hypothesis is based on the lifestyle of modern crocodilians and the stratigraphy of Baurusuchus. The anterior caudal vertebrae are robust as the sacral ones but their neural spines are more stout, anteriorlly expanded and higher. It was a terrestrial predator and scavenger, about 3. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. The proximal end possess a mesial projection that articulates itself to the illium, similar to those of Protosuchia and thecodont archosaurs as the Rauisuchia.

Retrieved from ” https: Most of the osteoderms are wider than longer, with a round lateral portion that does not articulate to any flank osteoderm.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. The femur is long when compared to extant crocodilians, showing a straight aspect in lateral view and a slight sigmoid aspect in frontal view. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.
The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. The anterior articular facet is discreet and the osteoderms are not as imbricated as occur in other crocodyliforms and even may not be imbricated at all. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. It was related to the earlier-named Cynodontosuchus rothiwhich was smaller, with weaker dentition. Basal notosuchians Uruguaysuchidae Anatosuchus Araripesuchus Uruguaysuchus.

This page was last edited on 10 Novemberat Both of this supports the terrestrial hypothesis. The salgadoensiss of the external nares was unsuited for an amphibious lifestyle like in modern crocodilians and the snout and teeth are laterally compressed like in theropods. From Wikimedia Commons, the free media repository. Cranial features indicate that this species had terrestrial predatory habits.

The sacral vertebrae are robust and have the lateral processes highly fused to the ilium. Major clades Ziphosuchia Sebecosuchia Sebecia. The illium of B. View all coordinates using: You may do so in any reasonable manner, but not in any way that suggests the licensor baurusuchjs you or your use.
From Wikimedia Commons, the free media repository. Baurusuchus is an extinct genus of baurusuchid mesoeucrocodylian from the Late Cretaceous of Brazil. The paper does not support its affiliation to Baurusuchus and views it as a close relative of Aplestosuchus.
