![]() ![]() Some portion of theropods eventually evolved into modern birds, but not all of them. Such is the case with Berthasaura leopoldinae, a recently discovered theropod from the Cemitério dos Pterossauros Quarry, in Brazil.Īs is the way with evolution, even these large dinosaur groups can be broken down further. However, there seems always to be an outlier who breaks all the rules. Basically, if it was sharp of tooth and ate other meat, it was probably a theropod. This last group contains many of your childhood favorites, nearly all of them carnivores, from T-rex and Velociraptor to Carnotaurus and Deinonychus. Among them are sauropods which contain the large, long-necked herbivores of Land Before Time fame ornithischians which contain many of the other well-known herbivorous dinosaurs like stegosaurus and theropods. Their findings were published in the journal Scientific Reports.ĭinosaurs can be broken up into a few main groups. Alexander Kellner from Laboratório de Sistemática e Tafonomia de Vertebrados Fósseis (LAPUG) in Brazil, and colleagues, described a previously unknown species of theropod dinosaur which is the first of its kind. But every new discovery adds a pixel to that every growing image.Ī recent discovery from a fossil bed in Brazil now adds information which not only fills a gap in our knowledge but changes the way we understand the evolution of a subset of dinosaurs, and it all comes down to their teeth, or the lack thereof. The nature of the fossil record - that so many of the plants and animals which have lived and died over the last few billion years should be lost to history - means that our knowledge is necessarily incomplete. Every new fossil found tells us not just about that individual animal, or even that animal’s species, but about the story of life on our planet. Every time we dig into the earth looking for bones, we peer into our own past. ![]()
