Even though it wasn't on the mainland, it is thought that Scleromochlus taylori was "the" ancestor of all pterosaurs on the islands. The first pterosaurs, much like on the mainland, were the Eopterosaurs. These small, insect hunting pterosaurs had short wings and thus poor flight. To add to this. they got tired quite quickly. They had plethora of threats to deal with, including small archosaurs, herrerasaurids, and the other pterosaurs on the island, the dimorphodonts. The dimorphodonts ariel hunting capabilities allowed them to quickly spread all over the island. These dimorphodonts quickly diversified into a plethora of forms, filter feeders, frugivores, and small insect specialists with long Toungs. This was known as the golden age of the dimorphodonts, and they held on strong to this title for 8 million years. During this time the dimorphodonts grew to sizes comparable to certain giant azhdarchids. However, the golden age was not to last, as the rausuchian era came to an end, while the last Saurosuchus Maximus closed its eyes for the last time, and while lisowicia shrank back down in size, two new groups of pterosaurs emerged to challenge the dimorphodonts.
