Taxonomy
The term Thalattosuchia was coined by Fraas in 1901.
Evolutionary history
Indeterminate remains possibly belonging to thalattosuchians have been reported from the Early Jurassic (Sinemurian) of Chile and France. However, they cannot be assigned to the group with confidence as they lack diagnostic characters.[9] In 2023 a basal teleosauroid was reported from the earliest Jurassic (Hettangian-Sinemurian) of Morocco, representing one of the oldest known thalattosuchians.[10] Turnersuchus from the Pliensbachian of England appears to be basal to both Teleosauroidea and Metriorhynchoidea.[9] While abundant during the Jurassic, their fossil record during the Early Cretaceous is scarce, and generally confined to low latitudes. The latest records of the group date to the Aptian.[11][12] Some members of Teleosauridae have been discovered in non-marine deposits.[4]
