Ichthyosauria, an Uncommon card

The card carries these facts from its Wikipedia article.

• Ichthyosaurians thrived during much of the Mesozoic era, based on fossil evidence, they first appeared around 250 million years ago and at least one species survived until about 94 million years ago, into the Late Cretaceous.
• During the Early Triassic epoch, ichthyosaurs and other ichthyosauromorphs evolved from a group of unidentified land reptiles that returned to the sea, in a development similar to how the mammalian land-dwelling ancestors of modern-day dolphins and whales returned to the sea millions of years later, which they gradually came to resemble in a case of convergent evolution.
• Ichthyosaurians were particularly abundant in the Late Triassic and Early Jurassic periods, until they were replaced as the top aquatic predators by another marine reptilian group, the Plesiosauria, in the later Jurassic and Early Cretaceous, though previous views of ichthyosaur decline during this period are probably overstated.
