BackgroundInsights into the onset of evolutionary novelties are key to the understanding of amniote origins and diversification. The possession of an impedance-matching tympanic middle ear is characteristic of all terrestrial vertebrates with a sophisticated hearing sense and an adaptively important feature of many modern terrestrial vertebrates. Whereas tympanic ears seem to have evolved. Osteology. STUDY. Flashcards. Learn. Write. Spell. Test. PLAY. Match. Gravity. Created by. saintcjacks. Dental Hygiene head and neck anatomy.

The line of descent that includes all living mammals extends back in time over million years. Many of the ancient relatives of mammals that fall along this line are very different in appearance from living mammals and are frequently mistaken for reptiles such as dinosaurs. This misconception is reinforced by the fact that these animals are often referred to as “mammal-like reptiles,” a.

As an undergraduate at the Université de Montréal, he focused on comparative anatomy and systematics and later received his PhD in the Department of Zoology at the University of Toronto, where he researched the osteology of seymouriamorphs and its implications for the origin of amniotes and where he was mentored and inspired by Robert by: 1.

Osteology, derived from the Greek words osteon.(bone) and logos (knowledge), is the scientific study of bones, practised by osteologists.A subdiscipline of anatomy, anthropology, and paleontology, osteology is a detailed study of the structure of bones, skeletal elements, teeth, microbone morphology, function, disease, pathology, the process of ossification (from cartilaginous molds), and the.

The air-breathing apparatus of tetrapods has its origin in gill breathing. The lungs of the first tetrapods were probably long and consisted of a single series of parenchyma-filled chambers, arranged along an intrapulmonary duct.
The duct gave rise to a broad central lumen in anurans. In amniotes a cartilaginous reinforcement by: Le CR2P est un laboratoire entièrement dédié à la a pour objectif d'élucider la structure des relations de parenté et l'histoire du vivant au travers du.
In an attempt to investigate differences between the most widely discussed hypotheses of early tetrapod relationships, we assembled a new data matrix including 90 taxa coded for 3.
Exact counts vary between hypotheses because there is controversy about the origin of lissamphibians and amniotes (e.g. Ruta and Coates, ; Marjanovi c and Laurin, ), but under all.

A long bone is one that is cylindrical in shape, being longer than it is in mind, however, that the term describes the shape of a bone, not its size. Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges).
Seymouria is an extinct genus of reptile-like tetrapods from the Early Permian of North America and Europe. Although they were amphibians (in a biological sense), Seymouria were well-adapted to life on land, with many reptilian features—so many, in fact, that Seymouria was first thought to be a primitive reptile.
It is primarily known from two species, Seymouria baylorensis and Seymouria. Smithson provides a summary of anthracosaurs in Chapter 5. The brevity of this chapter is odd given the significance of this group in considerations of the origin of amniotes and the apparent close relationship of anthracosaurs with seymouriamorphs.
Evolution in organisms occurs through changes in heritable traits—the inherited characteristics of an organism.
In humans, for example, eye colour is an inherited characteristic and an individual might inherit the "brown-eye trait" from one of their parents. Inherited traits are controlled by genes and the complete set of genes within an organism's genome (genetic material) is called its.
Ontogenetic series of extinct taxa are extremely rare and when preserved often incomplete and difficult to interpret. However, the fossil record of amphibians includes a number of well-preserved ontogenetic sequences for temnospondyl and lepospondyl taxa, which have provided valuable information about the development of these extinct groups.

Paleobiological implications of impedance matching Our study documents the first evidence of a true tympanic middle ear in Paleozoic amniotes (Figure 5), an evolutionary novelty that was hitherto believed to have evolved first in the Mesozoic , .
Seymouria baylorensis (BroiliLaurinKlembara J et al. ; Early Permian ~ mya, m in length) was so adapted to life on land that early workers considered it a reptile.
Derived from a sister to Eldeceeon, Seymouria phylogenetically preceded Utegenia and Silvanerpeton and was a sister to Kotlassia.
Distinct from Eoherpeton, the skull of Seymouria further raised the naris. The dermal bone sculpture (or ornament) of basal tetrapods, and its functional implications, remains one of the unresolved enigmas in vertebrate palaeontology.
Most of the Palaeozoic and Mesozoic stem tetrapods, temnospondyls, stem amniotes, and basal amniotes have dermal bones that are conspicuously sculptured by tubercles, pits, ridges, and.Osteology is the study of bones, both human and animal, in the archaeological record.
Osteologists study bones to identity their species, age, sex, and both pre- and post-mortem trauma, such as butchering. Osteologists may work with complete specimens or only bone fragments, and need to learn to identify specific bones and species from less.Anatomy of the basal theropod Tawa hallae and its implications for early dinosaur phylogeny.
