Not a lot is known about Anarosaurus due to the very fragmentary remains that are all we currently have. What can be ascertained from the remains however is that Anarosaurus was a pachypleurosaur, small reptiles that in appearance looked somewhere between terrestrial lizards and fully aquatic plesiosaurs. With this in mind Anarosaurus would have been a coastal animal that probably fed in the water, but returned to land to rest.
