New records from Banks Island expand the diversity of Eocene fishes from Canada’s western Arctic Greenhouse

Arctic Science, 2018
Eocene vertebrates from the Canadian Arctic, including sharks, bony fishes, turtles, crocodylians, birds, and mammals, have provided strong evidence for relatively warm ice-free conditions in the Arctic during the Eocene Greenhouse interval.

A new crocodylian from the late Maastrichtian of Spain: implications for the initial radiation of crocodyloids.

PLoS ONE, 2011
BackgroundThe earliest crocodylians are known primarily from the Late Cretaceous of North America and Europe. The representatives of Gavialoidea and Alligatoroidea are known in the Late Cretaceous of both continents, yet the biogeographic origins of ...

Crocodylian diversity peak and extinction in the late Cenozoic of the northern Neotropics [PDF]

, 2020
Northern South America and South East Asia are today’s hotspots of crocodylian diversity with up to six (mainly alligatorid) and four (mainly crocodylid) living species respectively, of which usually no more than two or three occur sympatrically.

Coordinate data of crocodylian crania (pre-superimposed)

, 2014
Coordinate data of 78 three-dimensional landmarks from 204 cranial specimens of 10 extant crocodylian species. All specimens, with the exception of Gavialis and Tomistoma, are from non-captive individuals.

A DIAGNOSIS OF ALLIGATOR MISSISSIPPIENSIS BITE MARKS WITH COMPARISONS TO EXISTING CROCODYLIAN DATASETS

, 2018
Crocodylians are known to consume and modify bones, but actualistic observations of their bite marks have been limited to forensic case studies and surveys of two taxa: Crocodylus niloticus and Crocodylus porosus.

Late Pleistocene (Rancholabrean) Glyptodont and Pampathere (Xenarthra, Cingulata) from Sonora, Mexico

Revista Mexicana de Ciencias Geológicas, 2018
The fossil-rich deposits of Térapa (east-central Sonora) contain more than 60 zoological taxa, many with tropical affinities such as Crocodylus (crocodylian), Hydrochaeris (capybara), and many birds.

First occurrences of neural canal ridges in Crocodylia

Acta Palaeontologica Polonica
Crocodylia is a crown group inclusive of the last common ancestor of extant crocodylians, followed by successive extinct and extant taxa forming Alligatoroidea, Crocodyloidea, and Gavialoidea.

Archelosaurian Color Vision, Parietal Eye Loss, and the Crocodylian Nocturnal Bottleneck [PDF]

, 2017
Vertebrate color vision has evolved partly through the modification of five ancestral visual opsin proteins via gene duplication, loss, and shifts in spectral sensitivity.

Habitat use and movement patterns of broad-snouted caimans (Caiman latirostris) in an impacted Atlantic forest environment in Brazil

Animal Biotelemetry
Background Animal habitat use can be influenced by a suite of factors including intraspecific interactions and resource availability. The broad-snouted caiman (Caiman latirostris) is the largest crocodylian species distributed in freshwater environments ...
