| | Brief history of the Dinosaurs |
| | The earliest known diapsid was Petrolacosaurus, and it was a moderately small animal, 60-70cm from snout to tail tip, with a long neck, large eyes, and long limbs, giving the impression of an agile terrestrial animal that probably fed on large insects and other arthropods. | | | The derived diapsids can be split into two groups, the Archosauromorpha and the Lepidosauromorpha. |

| | Archosauria: More on Morphology |
| | This is a bony process projecting posteriorly from the ankle joint that serves as an attachment point for some of the lower leg flexor muscles. | | | The archosaurs are characterized by numerous synapomorphies that lend strong support to the hypothesis that they form a monophyletic group (clade) exclusive of other Reptilia. | | | First of all, the "stem archosaurs" (properly termed Archosauromorpha), including Champsosauridae and Euparkeria, have a calcaneal tuber. |

| | Finally, Merck (1997) suggests that ichthyosaurs are the sister-group of sauropterygians, and that this clade is part of Archosauromorpha. | | | However, some taxa, such as ichthyosaurs and sauropterygians, have been variously thought to be stem-diapsids, lepidosauromorphs, or archosauromorphs, so their affinities are briefly discussed below. | | | In this tree, the position of ichthyosaurs and sauropterygians remains the same, but turtles move into lepidosauromorphs, as the sister-group of sauropterygians. |

| | Archosauromorpha -- The Dinosauricon |
| | Archosauromorpha includes all sauropsids with four-chambered hearts, an evolutionary innovation that permitted them higher activity levels and terrestrial dominance throughout the Mesozoic Era. | | | The forms shown here were once all included in Archosauria in the "grab-bag" taxon "Thecodontia" -- any archosaur that wasn't a crocodylian, a pterosaur, or a dinosaur. |

| | Brief History of the Dinosaurs |
| | Interestingly, another line of species derived from the Archosaurs, the Crurotarsi, gave rise to the only other extant group of Archosauromorpha, the Crocodylomorpha. | | | The Ornithodira, gave rise to the Dinosauria and to the Pterosauria. | | | The crocodiles evolved at about the same sort of time as the first Dinosaurs. |

| | Sauria - Wikipedia, the free encyclopedia |
| | The term "Sauria" has previously been used in a generic sense to refer to a suborder of Squamata, including the lizards ( Lacertilia) as opposed to the snakes ( Ophidia), but this classification is no longer used, as Sauria so-defined is a paraphyletic group. | | | The clade is defined by a number of details in skull and skeleton, and include the two important clades Lepidosauromorpha and Archosauromorpha. |

| | ARCHOSAUROMORPH CONTENTS |
| | What used to be called 'eosuchians' are now placed variously amongst the prolacertiform archosauromorphs (e.g. | | | > Archosauromorpha, Lepidosauromorpha (lizards, snakes, sphenodonts, > ?placodonts, ?plesiosaurs, ?nothosaurs, ?ichthyosaurs), and Eosuchia > (early diapsids; paraphyletic, I think, although I do not have specifics) No way are sauropterygians and/or ichthyosaurs part of the Lepidosauromorpha, IMHO anyway. | | | I can only guess that they are too aberrant to be including in many 'standard' cladograms (they _are_ mysteriously left out of many), but they definitely have the archosauromorph 'gestalt' for me... |

| | Ornithodira -- The Dinosauricon |
| | There are two possible non-pterosaurian pterosauromorphs: Sharovipteryx, an animal which may have glided on membranes supported by its hindlimbs; and Scleromochlus, a small, poorly understood creature. | | | It has been suggested that the fur-like integument seen in some pterosaur fossils and the feathers seen in some dinosaurs (fossil and living) might be homologous. | | | Some do not consider pterosaurs to be close relatives of dinosaurs: Archosauromorpha The Pterosaur Home Page |

| | Based on this phylogenetic tree, one can make the prediction that the genetic sequences responsible for the same proteins in birds, crocodiles, and snakes will be more similar between birds and crocodiles than between snakes and crocodiles. | | | The evolutionary phylogenic tree of life contains the following two distinct groups: the Lepidosauromorpha (comprised of lizards and snakes) and the Archosauromorpha (which contains crocodiles, birds, and dinosaurs). | | | Are you saying Dr. Safarti knows less about the phylogenetic tree than I, a non-scientist, do? |

| | From Dinosaurs to Birds |
| | The ascendancy of dinosaurs on land transpired rather rapidly some 215 million years ago, before the close of the Triassic. | | | The Diapsida split into several now extinct groups and eventually split again into the Lepidosauromorpha and Archosauromorpha. | | | The Lepidosauromorpha is comprised of lizards, snakes and their extinct relatives, while the Archosauromorpha is comprised of the crocodiles, pterosaurs, and dinosaurs (including birds). |

| | Cladistics - EvoWiki |
| | Under a typological system such as Linne used, however, a form like Archaeopteryx cannot be both reptile and bird; it can only be one or the other. | | | And yet, it has been evident since 1861 that birds are derived from ancestral stock somewhere within Archosauromorpha, and are therefore nested within Reptilia. | | | Including birds and defining the avian lineage such that it is nested within Archosauromorpha and Reptilia as a whole can resurrect Reptilia as a valid taxonomic category. |
