Acaenasuchus geoffreyi (Archosauria:Aetosauria) from the Upper Triassic Chinle Group: Juvenile of Desmatosuchus haplocerus

  title={Acaenasuchus geoffreyi (Archosauria:Aetosauria) from the Upper Triassic Chinle Group: Juvenile of Desmatosuchus haplocerus},
  author={Andrew B. Heckert},
Aetosaur scutes assigned to Acaenasuchus geoffreyi Long and Murry, 1995, are juvenile scutes of Desmatosuchus haplocerus (Cope, 1892), so A. geoffreyi is a junior subjective synonym of D. haplocerus. Scutes previously assigned to Acaenasuchus lack anterior bars and a strong radial pattern of elongate pits and ridges, but do possess an anterior lamina and a raised boss emanating from the mid-dorsal surface of the scute. Desmatosuchus is the only aetosaur with this combination of features, and…

A New Desmatosuchine Aetosaur (Archosauria: Suchia) from the Upper Triassic Tecovas Formation (Dockum Group) of Texas
The recognition of morphologically distinct specimens such as the holotype and referred material of Sierritasuchus demonstrates that past practices of assigning aetosaur specimens to known taxa based on superficial resemblance has masked diversity in this clade.
Skeletal Anatomy of Acaenasuchus geoffreyi Long and Murry, 1995 (Archosauria: Pseudosuchia) and its Implications for the Origin of the Aetosaurian Carapace
New fossils of Acaenasuchus geoffreyi are described that represent cranial, vertebral, and appendicular elements as well as previously unknown variations in the dorsal carapace and ventral shield, demonstrating the danger of using only armor character states in aetosaur taxonomy and phylogeny.
Intraspecific variation in the axial skeleton of Aetosauroides scagliai (Archosauria: Aetosauria) and its implications for the aetosaur diversity of the Late Triassic of Brazil.
The results shrink the number of putative 'dwarf' aetosaurs, indicating that morphological variation related to ontogeny affects aetosaur taxonomy and phylogeny.
A New Aetosaur (Archosauria, Suchia) from the Upper Triassic Pekin Formation, Deep River Basin, North Carolina, U.S.A., and Its Implications for Early Aetosaur Evolution
ABSTRACT Aetosaurs are an extinct clade of quadrupedal, heavily armored archosaurs that had a worldwide distribution during the Late Triassic. Aetosaur fossils from the Upper Triassic Pekin
A new species of the enigmatic archosauromorph Doswellia from the Upper Triassic Bluewater Creek Formation, New Mexico, USA
Doswellia sixmilensis is a new species of the dos-welliid archosauromorph genus Doswellia named for an incomplete skeleton from the Upper Triassic Bluewater Creek Formation of the Chinle Group in
First records of diapsid Palacrodon from the Norian, Late Triassic Chinle Formation of Arizona, and their biogeographic implications
Vertebrates from the Triassic Period have broadly disparate tooth shapes and dentition patterns, the result of intense morphospace experimentation following the Permo-Triassic extinction. Here, we
Aetosauria: a clade of armoured pseudosuchians from the Upper Triassic continental beds
Aetosauria is a clade of obligately quadrupedal, heavily armoured pseudosuchians known from Upper Triassic strata on every modern continent except Australia and Antarctica, and there is increasing evidence that at least some aetosaurs relied on invertebrates and/or small vertebrates as a food source.
A large, pathological skeleton of Smilosuchus gregorii (Archosauriformes: Phytosauria) from the Upper Triassic of Arizona, U.S.A., with discussion of the paleobiological implications of paleopathology in fossil archosauromorphs
A well-preserved specimen from Adamanian strata in Arizona that includes not only the skull and lower jaws but much of the postcranial skeleton, which exhibits extensive evidence of pathologies, including more osteomyelitis-like paleopathological elements than any other fossil archosaur.
We describe for the first time small «25 mm) dorsal paramedian, lateral, and appendicular /ventral scutes (osteoderms) of aetosaurs from the Blue Hills in Apache County, east-central Arizona. These
Triassic vertebrate fossils in Arizona
The Triassic System in Arizona has yielded numerous world-class fossil specimens, including numerous type specimens. The oldest Triassic vertebrates from Arizona are footprints and (largely)


A new aetosaur (Reptilia: Archosauria) from the Upper Triassic of Texas and the phylogeny of aetosaurs
Detailed phylogenetic analysis reveals that several North American aetosaur taxa are junior subjective synonyms of previously named taxa.
Redescription of Redondasuchus reseri,, a Late Triassic aetosaur (Reptilia: Archosauria) from New Mexico (U.S.A.), and the biochronology and phylogeny of aetosaurs
Abstract The Late Triassic (Rhaetian) aetosaur Redondasuchus reseri from the Redonda Formation of eastern NewMexico, U.S.A. is distinguished from all other aetosaurs except Typothorax by its
A new species of Desmatosuchus (Archosauria: Aetosauria) from the Upper Triassic of the Chama basin, north-central New Mexico.
We describe a new species of the aetosaur Desmatosuchus, D. chamaensis, from the Upper Triassic Snyder quarry, Petrified Forest Formation of the Chinle Group, Chama basin of north-central New
Cranial osteology of Longosuchus meadei and the phylogeny and distribution of the Aetosauria
The structure of the single well preserved skull was restudied in light of the appearance of new material of other archosaurs subsequent to Sawin's original description, and an ossified orbitosphenoid and several structures associated with the nasolacrimal duct system are described and discussed for the first time.
Preliminary Description of a New Suborder of Phytosaurian Reptiles with a Description of a New Species of Phytosaurus
The Triassic beds exposed in a narrow strip along the eastern edge of the Staked Plains in western Texas have not been intensively studied and are now grouped together under the name given by Drake,
Taphonomy and Depositional Setting of the Placerias Quarry (Chinle Formation: Late Triassic, Arizona)

The view is put forward that Acrocanthosaurus is a Lower Cretaceous representative of the tyrannosaur group, using this term in a broad sense, and is perhaps related to the Cenomanian Spinosaurus and the Wealden Altispinax.
Global Triassic tetrapod biostratigraphy and biochronology
Abstract Eight, temporally successive assemblage zones of tetrapod fossils provide the basis for dividing Triassic time into eight land-vertebrate faunachrons. These land-vertebrate faunachrons,
