ABSTRACT Despite the fact that fossil crocodylians have been recovered from the Panama Canal Zone starting with initial excavations in 1912, detailed studies have been lacking. Recent excavations of the canal have resulted in new discoveries of many vertebrate fossils, including the first known Miocene crocodylian skulls from Central America. These fossil skulls from the early-middle Miocene represent two new taxa with distinct morphology that is shared with extinct and extant caimans… Expand

Redescription and phylogenetic affinities of the caimanine Eocaiman cavernensis (Crocodylia, Alligatoroidea) from the Eocene of Argentina
Caimaninae is one of the few crocodylian lineages that still has living representatives. Today, most of its six extant species are restricted to South and Central America. However, recent discoveries… Expand
A new caimanine (Crocodylia, Alligatoroidea) species from the Solimões Formation of Brazil and the phylogeny of Caimaninae
ABSTRACT The Miocene deposits of South America are notable for their diverse crocodyliform fauna, of which the giant caimanine Purussaurus is a well-known example. This contribution describes a new… Expand
Lower Miocene alligatoroids (Crocodylia) from the Castillo Formation, northwest of Venezuela
Crocodyliform diversity was particularly high during the middle and late Miocene of South America, with up to 12 species recovered from a single geological unit. Nonetheless, the early Miocene fossil… Expand
Character evolution and the origin of Caimaninae (Crocodylia) in the New World Tropics: new evidence from the Miocene of Panama and Venezuela
TLDR
The persistence of two basal taxa into the Miocene of northern South America and Central America supports the concept of a relict basal population in this region, and supports biogeographic hypotheses of dispersals in both directions between North and South America prior to full land connection. Expand
A new species of Bottosaurus (Alligatoroidea: Caimaninae) from the Black Peaks Formation (Palaeocene) of Texas indicates an early radiation of North American caimanines
TLDR
A new caimanine from lower Palaeocene (Tiffanian) deposits in the Black Peaks Formation of Brewster County, Texas is established upon two specimens of different size that bear similarities to Bottosaurus harlani, indicating an early radiation of North American caimanines and elucidates a more complicated biogeographical history than previously hypothesized. Expand
A new Palaeocene crocodylian from southern Argentina sheds light on the early history of caimanines
TLDR
A new caimanine from this same unit represented by a skull roof and partial braincase is reported, showing that the Cretaceous and Palaeocene species of the group were more widespread than thought and became regionally extinct in North America around the CRETaceous–Palaeocene boundary. Expand
THE ALLIGATOROIDEA OF ARGENTINA: AN UPDATE OF ITS FOSSIL RECORD
The fossil record of Alligatoroidea in Argentina is mainly represented by Caimaninae alligatorids. This lineage recorded two impor- tant moments in its natural history, one at the beginning of the… Expand
Enigmatic Crocodyliforms from the Early Miocene of Cuba
ABSTRACT Early Miocene deposits from the Domo de Zaza locality, in the south-central Cuban province of Sancti Spiritus, preserve crocodyliform remains, including compressed serrated teeth closely… Expand
The crocodylomorph fauna of the Cenozoic of South America and its evolutionary history: a review
Abstract The fossil crocodylomorph fauna of the Cenozoic of South America is very rich and diverse. Historically, few publications have been dedicated to providing an overall review of this fauna,… Expand
The late Miocene caimanine fauna (Crocodylia: Alligatoroidea) of the Urumaco Formation, Venezuela
The late Miocene Urumaco Formation at Urumaco, Falcón state, Venezuela, is remarkably rich in extinct crocodylians, presenting a diversity hotspot in the Neotropics for the group. Herein, we revise… Expand

A new giant Purussaurus (Crocodyliformes, Alligatoridae) from the Upper Miocene Urumaco Formation, Venezuela
TLDR
A phylogenetic analysis of 164 characters in 68 ingroup crocodile taxa supported the association of P. neivensis and P. mirandai with five synapomorphies and confirmed the sister‐group relationship of the genus with the Nettosuchidae. Expand

TLDR
A phylogenetic analysis suggest that Trilophosuchus is most closely related to four other Australian taxa of extinct crocodilians and should be included in the Australian Tertiary crocodilian radiation. Expand

Mitochondrial DNA phylogeography of Caiman crocodilus in Mesoamerica and South America.
TLDR
The molecular phylogenetic results identified five mtDNA haplotype clades with a mean sequence divergence of 3.4%, indicating considerable evolutionary independence among phylogeographic lineages, and confirm the status of C. c. Expand
Ancient Nursery Area for the Extinct Giant Shark Megalodon from the Miocene of Panama
TLDR
It is proposed that the Miocene Gatun Formation represents the first documented paleo-nursery area for C. megalodon from the Neotropics, and one of the few recorded in the fossil record for an extinct selachian. Expand

Historical zoogeography of the eusuchian crocodilians: a physiological perspective
TLDR
It is proposed that Gavialis and Tomistoma, now restricted to fresh waters, may have been derived secondarily from ancestors adapted to salt water, and that anatomical and physiological adaptations to a marine existence have played an important role in eusuchian history. Expand
