ABSTRACT The fossil record of dyrosaurid crocodyliforms spans the Late Cretaceous to Middle Eocene of Africa, Asia, Europe, North America, and South America. Prior to this study, specimens from South America have been limited to a few fossils with only two taxa diagnosed. We describe a nearly complete skull and unassociated mandible of a new dyrosaurid, Cerrejonisuchus improcerus gen. et sp. nov., from the Paleocene Cerrejón Formation of northeastern Colombia. The skull of C. improcerus has… 
A new longirostrine dyrosaurid (Crocodylomorpha, Mesoeucrocodylia) from the Paleocene of north‐eastern Colombia: biogeographic and behavioural implications for New‐World Dyrosauridae
TLDR
Acherontisuchus guajiraensis is distinct among known dyrosaurids in having a unique combination of craniomandibular characteristics, and postcranial morphology that suggests it may have occupied a more placid, fluvial habitat than most known Old-World dy- rosaurids.
A new blunt-snouted dyrosaurid, Anthracosuchus balrogus gen. et sp. nov. (Crocodylomorpha, Mesoeucrocodylia), from the Palaeocene of Colombia
TLDR
A new exceptionally brevirostrine dyrosaurid is described from the middle Palaeocene Cerrejón Formation, northeastern Colombia, based on four partial skulls and associated postcrania, which indicates a deviation from surface-based predation to sub-surface predation as in modern Gavialis.
Brachiosuchus kababishensis, a new long-snouted dyrosaurid (Mesoeucrocodylia) from the Late Cretaceous of north central Sudan
ABSTRACT Here we report on a new dyrosaurid from the latest Cretaceous Kababish Formation, Sudan, which was previously unknown to yield fossil macrovertebrates and had remained largely unstudied. The
First Record of Hyposaurus (Dyrosauridae, Crocodyliformes) from the Upper Cretaceous Shendi Formation of Sudan
TLDR
The occurrence of Hyposaurus within the Shendi Formation represents the first record of this genus from the Late Cretaceous of Africa and potentially extends its temporal range to the Campanian.
The postcranial skeleton of Cerrejonisuchus improcerus (Crocodyliformes: Dyrosauridae) and the unusual anatomy of dyrosaurids
TLDR
The data reveal the existence of a distinctive postcranial anatomy for Dyrosauridae that is markedly distinct from that of crocodylians, and indicates a more terrestrial lifestyle for Cerrejonisuchus compared to the derived members of the clade.
Sabinosuchus coahuilensis, A New Dyrosaurid Crocodyliform from the Escondido Formation (Maastrichtian) of Coahuila, Mexico
TLDR
Sabinosuchus coahuilensis joins Hyposaurus rogersii as the second known North American dyrosaurid and Phylogenetic analyses and biostratigraphy suggest that S. coahuILensis occupies a basal position in Dyrosauridae.
Revision of the Baurusuchidae Family and its phylogenetic affinities within Mesoeucrocodylia
TLDR
An anatomical cranial redescription of the Baurusuchidae family is presented, as well as a phylogenetic analysis constructed based on a dataset of 386 characters and 81 taxa, with all known baurusuchids among them, finding a monophyletic Baurusuchi clade, strongly supported by fourteen synapomorphies, and a Bergisuchidae clade as its sister group, both within a more inclusive clade Sebecosuchia.
New dyrosaurid remains (Crocodyliformes, Mesoeucrocodylia) from the Paleocene of the Paraíba Basin, NE Brazil
The fossil crocodyliforms from the Paraíba Basin in Northeastern Brazil are represented by two species, Hyposaurus derbianus, (uncertain age) and Guarinisuchus munizi, from the Paleocene Maria

TLDR
A phylogenetic analysis of the dyrosaurids indicates a close relationship between A. coupatezi and Rhabdognathus and confirms a previous hypothesis that Congosaurus is distinct from Hyposaurus.

A new species of Dyrosaurus (Crocodylomorpha, Dyrosauridae) from the early Eocene of Morocco: phylogenetic implications
TLDR
A phylogenetic analysis shows the dyrosaurids as the sister taxon of pholidosaurids, which include Elosuchus, Sarcosuchu, Terminonaris and Pholidosaurus, and the thalattosuchians, and a non-monophyletic group; however, phylogenetic problems remain with respect to longirostrine clade, and more attention should be paid to resolving their evolutionary relationships amongst the crocodyliforms.
Congosaurus bequaerti, a Paleocene Dyrosaurid (Crocodyliformes; Mesoeucrocodylia) from Landana (Angola)
TLDR
Characters suggest that Congosaurus bequaerti should be distinguished from Hyposaurus and Rhabdognathus, and then, the original DOLLO'S genus should be retained for this species.
A NEW SPECIES OF ARARIPESUCHUS (CROCODYLOMORPHA, MESOEUCROCODYLIA) FROM THE LOWER CRETACEOUS OF PATAGONIA (ARGENTINA)
TLDR
Araripesuchus is proposed here as being the sister taxon of Neosuchia, corroborating previous phylogenetic analysis and allowing a reanalysis of the role played by their amphiatlantic distribution in the Aptian-Albian.

TLDR
An emended diagnosis is given for D. phosphaticus, the only known species of this genus and new characteristics that enable comparisons with other crocodyliforms are available.
