The Habitat of the Crocodilia of British Guiana
Ecology, 1923The Crocodilia of British Guiana consist, apparently, of four species of Caiman, of which only the black caiman, C. niger, reaches a large size and is supposed to be dangerous to man. The smaller species were studied in three regions: (i) in the jungle some forty miles from the coast; (2) in the parks and sugar estates in the neighborhood of Georgetown;

Characterization of dentin matrix protein 1 gene in crocodilia
Gene, 1999Several clones containing DMP1 cDNA were isolated from a caiman tooth library by screening with a platypus DMP1 probe. The caiman DMP1 shows little amino acid sequence similarity to mammalian DMP1s for much of its length. A few highly conserved regions can, however, be identified that correspond to the slowly evolving parts of the corresponding ...

Attachment tissues of the teeth in Caiman sclerops (Crocodilia)
Journal of Zoology, 1979As the Crocodilia are the only non‐mammalian vertebrates with tooth sockets, the attachment tissues of the teeth were studied in Caiman sclerops mainly at the ultrastructural level and were compared with those of mammals. All three attachment tissues (alveolar bone, cementum and periodontal ligament) in the Caiman showed both similarities and ...

Eocene ziphodont crocodilia from Northwestern India
Geobios, 1978The Middle Eocene (Lutetian) strata constituting the top of the Subathu Formation in Jammu and Kashmir, have yielded a large number of ziphodont crocodilians. The affinity of these serrated-toothed crocodiles has been assigned to the Eusuchian Pristichampsus rather than to the Sebecosuchia.

Managing the Crocodilia: an integrated approach
1997Crocodilians are the only living members of the Archosauria, an ancient group of reptiles which included the dinosaurs and the progenitors of birds. Existing species, of which there are about 22 (depending on determination of subspecies) occur throughout the tropics and subtropics, and most authorities classify them, on the basis of snout proportions ...

DNA fingerprinting in reptiles: Bkm hybridization patterns in Crocodilia and Chelonia
Genome, 1991The simple tetranucleotide repeat GATA (GACA) occurs in all eukaryotes so far studied. In many species, the arrangement of these sequences varies considerably among individuals. Thus GATA (GACA) type probes produce DNA fingerprints when hybridized with restricted DNA from different individuals within a species.

Global diversity of crocodiles (Crocodilia, Reptilia) in freshwater
Hydrobiologia, 2007Living crocodilians include the 24 species of alligators, caimans, crocodiles and gharials. These large semi-aquatic ambush predators are ubiquitous in freshwater ecosystems throughout the world’s tropics and warm temperate regions. Extant crocodilian diversity is low, but the group has a rich fossil record in every continental deposit.
