Crocodiles today are famous for their amphibious habits, but only a few actually live in water more than a few metres deep. However, the largest and least endangered of the crocodiles, the indo-pacific saltwater crocodile, is one of the few that does go into salt water, and with that advantage over other crocodilians, it could form a new lineage of oceanic crocodiles. Hence, this concept.
Pelagocrocodylus is a possible and potentially plausible descendant of the saltwater crocodile that lives in the Indo-Pacific oceanic zone in the coming 5 - 15 million years, and is almost totally marine, with the exception of coming to shore to lay eggs and occasionally bask. There are several species in the genus, all of which are able to tolerate salt w…

This is a new group I have thought up for Future of The World, because it's kind of gone inactive again, and I think it needs a new spark.
The group I have come up with are the Volgaraptoria, basically a collective group of mostly* small gubernators that are more like small birds than pterosaurs. Looking at the gubernatoroidea now, nearly all of the ones that are currently in the project are massive, with wingspans that are at least 6 metres. But looking at birds in real life, as well as pterosaurs, most species were/are not big, and most are actually really small. So it makes sense that the gubernatoroidea, being the next group of volant tetrapods, would follow a similar pattern of size. Hence, this blog post.
The Volgaraptoria split off fr…Read more >
Today, the Mediterranean is an almost landlocked ocean basin, the last large remnant of the Tethys Ocean. But several million years ago, it was a toxic lake of salt more than 2 km below sea level, where only brine flies and microbes could live long term. But this was not to last, some 100,000 years after it was first isolated, the entire basin was flooded in only a few years when the Atlantic broke through at Gibraltar, in a flood that is believed to have been one of the largest in the earths history. But as Africa continues to slowly move northwards, it seems inevitable that this will happen again.
In some 6 million years time, at the height of the 'EPIA' (Early Postocene Ice Age) the combination of low sea levels and the closing of the Gi…Read more >

Ever since the Triassic, when the first ichthyosaurs and sauropterygians set foot in the water, the seas have been the domain of the tetraopds. These early marine reptiles greately diversified and with few interruptions they persisted until the end of the cretaceous, when they were themselves the victim of a mass extinction. After this event, the mammals took over this role, and the whales, seals, sirenians and otters, amongst several extinct groups, have largely dominated the seas since then.
The reptiles and birds still, however, exist in the seas in relative abundance, the birds as a variety of flightless and volant seabird…Read more >
This is not a project, but an idea I had ~KaptainWombat
In the world we live in, the mammals are dominant, and have been since the end of the cretaceous, when non-avian dinosaurs went extinct. Reptiles are still very much presant, and still soldier on as the crocodilians and squamates, with the tuatara of New Zealand representing a third group. But suppose that one other group of reptiles evolved in the mesozoic, and persisted to the presant? These reptiles are new, different, and have one highly distinctive feature. Living on most continents, in the sea, and even in the air, they have made this world quite different from the familiar cenozoic.
The Declinozoic is in most ways the same as the Cenozoic we're used to, with the megafauna being m…
