Sauropterygians were a diverse group of aquatic reptiles adapted for flipper-based aquatic locomotion. This group included the plesiosaurs, nothosaurs, and placodonts. Mosasaurs were a group of large, aquatic squamates (relatives of modern-day lizards and snakes) which became the dominant marine predators towards the end of the Cretaceous period.
A fish with limb-like fins that could take it onto land. [75] It is an example from several lines of ancient sarcopterygian fish developing adaptations to the oxygen-poor shallow-water habitats of its time, which led to the evolution of tetrapods. [61]
The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of gymnosperms such as cycads, ginkgoaceae and araucarian conifers, and of archosaurian reptiles such as the dinosaurs; a hot greenhouse climate; and the tectonic break-up of Pangaea.
The name "phytosaur" means "plant lizard", as the first fossils of phytosaurs were mistakenly thought to belong to plant eaters. [ 3 ] For many years, phytosaurs were considered to be the most basal group of Pseudosuchia (crocodile-line archosaurs ), meaning that they were thought to be more closely related to the crocodilians than to birds ...

[14] [15] However, in 1817, Karl Dietrich Eberhard Koenig had already referred to the animal as Ichthyosaurus, "fish saurian" from Greek ἰχθύς, ichthys, "fish". This name at the time was an invalid nomen nudum and was only published by Koenig in 1825, [16] but was adopted by De la Beche in 1819 in a lecture where he named three ...
Like the largest fish today, the whale sharks and basking sharks, Leedsichthys problematicus derived its nutrition as a suspension feeder, using an array of specialised gill rakers lining its gill basket to extract zooplankton, small animals, from the water passing through its mouth and across its gills.
