Crocodile Evolution: A Thalatosuchian Resurrection?

Mar 24, 2021 · taxonomically diverse and ecologically divergent mesozoic crocodylomorphs, like marine thalattosuchians and terrestrial notosuchians, rapidly evolved novel skull and jaw. Our analysis reveals that reproductive trait evolution in crocodilians reflects phylogenetic constraint (nest attendance, nest defense), ecological convergence (seasonal timing of. From the lower jurassic. Jan 24, 2019 · based on the pattern of transitions to the marine realm, our analysis suggests at least four independent origins of saltwater tolerance in crocodylomorpha. Here, we unravel the remarkably entangled evolutionary history of wall lizards by sequencing genomes of 34 major lineages covering 26 species.

When scientific paleontology came of age early in the 19th century, fossil croc odiles were among the first vertebrate animals to be unearthed, and even today new fossil crocodilians are. Phylogenetic analyses of two published datasets recover turnersuchus as the earliest diverging thalattosuchian, and sister to teleosauroidea + metriorhynchoidea.
