described as a species of the polycotylid plesiosaur
T. lafquenianum was later re-described as a
distinct genus of short
necked elasmosaurid plesiosaur. Kawanectes is
similar to the larger
Because the bones in Kawanectes have complete
them, we can tell that Kawanectes was fully grown
at the time of
death, and thus cannot be the younger form of Vegasaurus.
