The study and article I read showed some convincing evidence.
The amino acid chains sample were consistent with control samples of blue sharks.
older shark carcasses have well-calcified cartilage structures, thus the bony consistency of the skeletal structure.
The vertebrae count is wrong for all known pleiosaurs... even the short-necked ones.
red muscle is not as common in sharks, but is prevalent in basking sharks due to their slow motion swim style.
so.. Shark for me.
