For more than years dinosaurs have been classified into two distinct orders, the saurischians and the ornithischians. What are evolutionary tree in biology as it is common in biological sciences, every theory is true until the opposite is proved. A new study has called into question classical dinosaur classification, destroying and redistributing some of the different dinosaur groups. Since the XIX century, dinosaurs have been divided into two large orders based on their hip anatomy.

The order Saurischia lizard-hipped what are evolutionary tree in biology theropods carnivorous dinosaurs and current birds and sauropodomorphs large, long-necked herbivores ; the order Ornithischia bird-hipped includes ornithopods herbivorous and duck-billed dinosaursmarginocephalians dinosaurs with horns and hardened skulls and thyreophorans armored dinosaurs.

This is what has recently happened with dinosaurs. A new study published in Marchhas caused the reconsideration of traditional dinosaur classification. However, this new study has pioneered in many aspects:. This study has detached from many of the previous assumptions on dinosaur phylogeny and has analysed a large number of species and many characters not included in previous investigations.

This has made the resulting evolutionary tree pretty different from the ones obtained before. Well, the matter is somewhat complex, even if the different groups are still divided what are evolutionary tree in biology two orders:. What are evolutionary tree in biology order Saurischia is almost the same, except that theropods are no longer part of this group. According to this new hypothesis, herrerasaurids and sauropodomorphs are all included as saurischians.

Herrerasaurids Herrerasauridae family were a small group of basal saurischians that evolved towards meat-eating. Even if they were pretty specialized, they were probably displaced by competition with other predators, appearing during the middle Triassic and becoming extinct at the end of it. Herrerasaurids occupied a similar ecological niche as theropods. The new hypothesis implies that hypercarnivory feeding exclusively on meat evolved independently twice in dinosaurswhich makes some palaeontologist question it.

Yet the herrerasaurid and what is the meaning of the word girl lover anatomy differed in some aspects, such as the anatomy of their hands more generalistic in herrerasaurids and the jaw structure. The first sauropodomorphs were biped animals just like herrerasaurids, even if they were omnivorous. Yet, sauropodomorphs would end up becoming huge herbivorous quadrupeds with characteristic long necks.

The new dinosaur order is Ornithoscelidawhich groups theropods with ornithischians. This taxon is supported by more than twenty skeletal synapomorphies derived characters shared by a cladepresent both in basal theropods and ornithischians. Some of these characteristics include the presence of a gap between premaxillar and maxillar teeth diastema and the fusion of the ends of the tibia and the fibula into a tibiotarsus even if these characteristics are only found on the most basal species.

Both theropods and the first ornithischians were bipedal animals. Also, the presence of heterodont teeth in the ancestral members of both groups leads us to think that the first ornithoscelidans were omnivorous, which would later specialise in feeding on meat what are evolutionary tree in biology on plants theropods and ornithopods respectively. A curiosity about the new classification is that accepting Ornithoscelida as a valid taxon, all feathered dinosaurs are put together into one group.

Then, is this hypothesis irrevocable? Well, no of course. Even if this study shows really interesting results about the origin of dinosaurs, we cannot dismiss hundreds of previous studies about this group of animals. And that with new investigation techniques and new discoveries, little by little we learn more about the world around us.

Traditional dinosaur evolutionary tree by Zurekswith the two different hip morphologies at the bottom.

However, this new study has pioneered in many aspects: It includes a larger number of species and taxons many more than in previous investigations. Previous studies gave more importance to basal theropod and sauropodomorph dinosaurs traditional saurischiansas they were the first dinosaurs to diversify, including few basal ornithischians. It has also included many dinosauromorph archosaurs non-dinosaur taxons. Older studies had assumed many ornithischian characters to be symplesiomorphies ancestral characters of all dinosaurs and they only focused on a few synapomorphies characters found in a monophyletic group.

Well, the matter is somewhat complex, even if the different groups are still divided in two orders: Order Saurischia which, according to what are evolutionary tree in biology study, only includes sauropodomorphs and herrerasaurids a group of carnivorous, non-theropod saurischians. The new order Ornithoscelida bird-limbed that includes the traditional ornithischians and theropods, which are no longer saurischians. Saurischians The order Saurischia is almost the same, except that theropods are no longer part of this group.

Even if it cannot be appreciated in this image, sauropodomorphs would increase very their size very much during their evolution Thecodontosaurus 2 metres, Plateosaurus up to 10 metres.
