The unidentified pliosaur is an unknown genus of Pliosaur that lived off the coast of Portugal in the late Jurassic.
In Walking with Dinosaurs (2025)[]
Island of Giants[]
A dead Pliosaur washed onto the shore, where a Torvosaurus scavenged the carcass. A second Torvosaurus challenged the first over the carcass until both where driven off by Old Grande the Lusotitan. After being initially defeated by the younger male Lusotitan, Old Grande fed on the remaining carcass of this pliosaur to heal his injury. The narration explains this as a behavior known as osteophagy, which is when herbivores eat the bones to obtain vital minerals.
