Anatomy and evolution of the Galápagos marine iguana, Amblyrhynchus cristatus (Squamata, Iguanidae), with a new phylogeny of Iguania and considerations about aquatic adaptations in extant and fossil lizards
DownloadFall 2021
Amblyrhynchus cristatus, the marine iguana, is unique amongst the ~7000 species of living limbed lizards as it has successfully evolved adaptations that allow it to live in both terrestrial and marine environments. This species is endemic to the Galápagos Archipelago and has evolved a specialized...

Lindgren, Johan, Everhart, Michael J., Caldwell, Michael W.
The physical properties of water and the environment it presents to its inhabitants provide stringent constraints and selection pressures affecting aquatic adaptation and evolution. Mosasaurs (a group of secondarily aquatic reptiles that occupied a broad array of predatory niches in the...
