While fans knew the rift between the former friends had to do with the death of Owen's sister, we finally learned the full backstory behind the "war" between the two docs. The trio's trip got off to a rocky start basically from the moment the key turned in the ignition, when Nathan revealed he bought Amelia Caterina Scorsone a drink a few months ago, not knowing she was an alcoholic. And that's when Owen dropped the truth bomb on her AND us. He wasn't anywhere near that chopper, he was off screwing some woman from supply court," Owen revealed.
The other groups mentioned are, like dinosaurs and pterosaurs, members of Sauropsida the reptile and bird cladewith the exception of Dimetrodon which is a synapsid. Definition Triceratops skeleton, Natural History Museum of Los Angeles County Under phylogenetic nomenclaturedinosaurs are usually defined as the group consisting of the most recent common ancestor MRCA of Triceratops and Neornithesand all its descendants.
In traditional taxonomy, birds were considered a separate class that had evolved from dinosaurs, a distinct superorder. However, a majority of contemporary paleontologists concerned with dinosaurs reject the traditional style of classification in favor of phylogenetic taxonomy; this approach requires that, for a group to be natural, all descendants of members of the group must be included in the group as well.
Birds are thus considered to be dinosaurs and dinosaurs are, therefore, not extinct. Norman, and Paul M. Barrett in suggested a radical revision of dinosaurian systematics.
Phylogenetic analysis by Baron et al. They resurrected the clade Ornithoscelida to refer to the group containing Ornithischia and Theropoda. Dinosauria itself was re-defined as the last common ancestor of Triceratops horridusPasser domesticusDiplodocus carnegiiand all of its descendants, to ensure that sauropods and kin remain included as dinosaurs.
Using one of the above definitions, dinosaurs can be generally described as archosaurs with hind limbs held erect beneath the body. Other groups of animals were restricted in size and niches; mammals, for example, rarely exceeded the size of a domestic cat, and were generally rodent-sized carnivores of small prey.
While dinosaurs were ancestrally bipedal as are all modern birdssome prehistoric species were quadrupeds, and others, such as Anchisaurus and Iguanodoncould walk just as easily on two or four legs.
Cranial modifications like horns and crests are common dinosaurian traits, and some extinct species had bony armor. Although known for large size, many Mesozoic dinosaurs were human-sized or smaller, and modern birds are generally small in size.
Dinosaurs today inhabit every continent, and fossils show that they had achieved global distribution by at least the early Jurassic period. Although some later groups of dinosaurs featured further modified versions of these traits, they are considered typical for Dinosauria; the earliest dinosaurs had them and passed them on to their descendants.
Such modifications, originating in the most recent common ancestor of a certain taxonomic group, are called the synapomorphies of such a group. Some of these are also present in silesauridswhich Nesbitt recovered as a sister group to Dinosauria, including a large anterior trochanter, metatarsals II and IV of subequal length, reduced contact between ischium and pubis, the presence of a cnemial crest on the tibia and of an ascending process on the astragalus, and many others.
However, because they are either common to other groups of archosaurs or were not present in all early dinosaurs, these features are not considered to be synapomorphies. For example, as diapsidsdinosaurs ancestrally had two pairs of temporal fenestrae openings in the skull behind the eyesand as members of the diapsid group Archosauria, had additional openings in the snout and lower jaw.
These include an elongated scapulaor shoulder blade; a sacrum composed of three or more fused vertebrae three are found in some other archosaurs, but only two are found in Herrerasaurus ;  and a perforate acetabulumor hip socket, with a hole at the center of its inside surface closed in Saturnaliafor example.
Dinosaurs may have appeared as early as million years ago, as evidenced by remains of the genus Nyasasaurus from that period, though known fossils of these animals are too fragmentary to tell if they are dinosaurs or very close dinosaurian relatives.
The terrestrial habitats were occupied by various types of archosauromorphs and therapsidslike cynodonts and rhynchosaurs.
Their main competitors were the pseudosuchiasuch as aetosaursornithosuchids and rauisuchianswhich were more successful than the dinosaurs. Rhynchosaurs and dicynodonts survived at least in some areas at least as late as early-mid Norian and early Rhaetianrespectively,   and the exact date of their extinction is uncertain.
These losses left behind a land fauna of crocodylomorphsdinosaurs, mammalspterosauriansand turtles. In the late Triassic and early Jurassic, the continents were connected as the single landmass Pangaeaand there was a worldwide dinosaur fauna mostly composed of coelophysoid carnivores and early sauropodomorph herbivores.
Early sauropodomorphs did not have sophisticated mechanisms for processing food in the mouth, and so must have employed other means of breaking down food farther along the digestive tract. Dinosaurs in China show some differences, with specialized sinraptorid theropods and unusual, long-necked sauropods like Mamenchisaurus.
Conifers and pteridophytes were the most common plants. Sauropods, like the earlier prosauropods, were not oral processors, but ornithischians were evolving various means of dealing with food in the mouth, including potential cheek -like organs to keep food in the mouth, and jaw motions to grind food.
The earliest part of this time saw the spread of ankylosaurians, iguanodontiansand brachiosaurids through Europe, North America, and northern Africa.
These were later supplemented or replaced in Africa by large spinosaurid and carcharodontosaurid theropods, and rebbachisaurid and titanosaurian sauropods, also found in South America.Memorial Fund for Owen Henderson - As many of you may know, Owen Henderson passed away on March 5th, Owen worked in Fund Accounting for over 10 years and was an integral part of the initial transition of the Boston team to Westlake, TX.
