... that Irritator is only known from a skull that was badly obscured by plaster which was added by the commercial fossil-collecting fossil-poachers who illegally sold it in hopes of making the fossil look more complete and valuable?
... that rhynchosaurs had unique teeth that were modified into broad tooth plates?
... that a trackway produced by an unknown crocodyliform that measured approximately 12 meters in length was uncovered in the Galve region of Spain?
Ichthyosaurs were giant marine reptiles that resembled fish and dolphins. Ichthyosaurs thrived during much of the Mesozoicera; based on fossil evidence, they first appeared approximately 245 million years ago (mya) and disappeared about 90 million years ago, about 25 million years before the dinosaurs became extinct. During the Middle TriassicPeriod, ichthyosaurs evolved from as-yet unidentified land reptiles that moved back into the water, in a development parallel to that of modern-day dolphins and whales. Ichthyosaurs were particularly abundant in the Jurassic Period, until they were replaced as the top aquatic predators by plesiosaurs in the Cretaceous Period. Ichthyosaurs averaged two to four meters in length (although a few were smaller, and some species grew much larger), with a porpoise-like head and a long, toothed snout. Ichthyosaur fossils have been found on every continent except Africa and Antarctica (other researchers reported finding possible ichthyosaur teeth in Antarctica, but they weren't enough to convince most paleontologists). They belong to the order known as Ichthyosauria or Ichthyopterygia ('fish flippers' - a designation introduced by Sir Richard Owen in 1840, although the term is now used more for the parent clade of the Ichthyosauria).
