Deciduous lower premolars (milk teeth) of the Eocene artiodactyl family Cebochoeridae possess accessory denticles and are remarkably similar to both deciduous and adult teeth of the cetacean family Basilosauridae, suggesting that morphological characters of juvenile dentitions are important to understanding the phylogenetic origin of whales and morphological transitions in the cetartiodactyl. Artiodactyl - Artiodactyl - Evolution and paleontology: The artiodactyls can be traced back to a probable descent from a group of early generalized mammals called condylarths and were certainly distinct by the Eocene Epoch, which ended about million years ago.

(). The hornless protoceratid Pseudoprotoceras (Artiodactyla: Tylopoda) in the early Oligocene of Saskatchewan and Wyoming. Journal of. Although Cenozoic protoceratid artiodactyls are known from throughout North America, species referred to the Miocene protoceratine Paratoceras are restricted to subtropical areas of the Gulf Coast.

Classification. Protoceratidae was erected by Othniel Charles Marsh inwith the type genus Protoceras and assigned to the Artiodactyla.

It was later assigned to Pecora, and more recently to Ruminantia or Tylopoda. However, recently a relationship to chevrotains in the infraorder Tragulina has been proposed. Morphology. When alive, protoceratids would have probably resembled deer, though. The artiodactyls are arguably the most successful order of large land mammals (as long as we don’t mention a dominant lone species of large aggressive primates).

Just perusing a list of artiodactyl names reveals how universal and important they are: goats, pigs, cows, giraffes, hippos, sheep, Protoceratidae wait.

Artiodactyls are diverse and successful hoofed mammals, represented by nearly two hundred living species of pigs, peccaries, hippos, camels, deer, sheep, cattle, giraffes, and other even-toed the recent years, a tremendous amount of research has been conducted on this important order. The Evolution of Artiodactyls synthesizes this research into a single, comprehensive volume.

ABSTRACT Observations of the holotype of Syndyoceras cooki and comparative material indicate that protoceratid basicrania share no striking resemblances to those of camelids, a group purported to be closely related to the protoceratids.

The protoceratid petrosal has a massive posterodorsal (canalicular) part with a strong dorsal crest separating the cerebral and cerebellar surfaces, like the. Neogene fossil artiodactyls with cranial appendages (Joeckel and Stavas, ). By the late Oligocene, male protoceratids exhibit a variety of cranial appendages that are unique among North American artiodactyls (Marsh, ; Prothero, ).

The far-reaching ramifications of the addition of cetaceans to the Artiodactyla are apparent in the numbers of chapters that cite the same problem nodes in the cladogram as they affect the need for research within different families of artiodactyls.

Originally, protoceratids were thought to be ruminants: Scott (, ) allied them with leptomerycids and/or hypertra-gulids (Fig. lA), a scheme somewhat mirrored by at least one modern analysis (Fig. lD).

This comprehensive review of the taxonomic relationships of artiodactyls and perissodactyls brings forth new evidence in order to propose a theory of ungulate taxonomy.

With this straightforward volume, Colin Groves and the late Peter Grubb cut through previous assumptions to define ungulate genera, species, and subspecies.

the Protoceratidae, an enigmatic group of selenodont artiodactyls. Until now Leptotragulus was known primarily from teeth, limb bones and a few skull fragments. A previously undescribed series of crania shows that Leptotragulus exhibits the typical protoceratid skull morphology, with a broad, flattened forehead, pronounced lambdoid crests.

Stratigraphy & Vertebrate Fauna of the Otibanda Formation, New Guinea. Board covers. Protoceras (meaning "first horns") is an extinct genus of protoceratid endemic to North America from the Oligocene through Miocene (Orellan to Harrisonian stage) — Ma, existing for approximately million years.

Taxonomy. Protoceras was named by Marsh (). Its type is Protoceras is the genus of Protoceratidae and subfamily Protoceratinae. Methodology/Principal Findings. We reexamine relationships of critical extinct taxa that impact our understanding of the origin of Cetacea.

We do this in the context of the largest total evidence analysis of morphological and molecular information for Artiodactyla ( phenotypic characters molecular characters, coded for 33 extant and 48 extinct taxa).

able that the early artiodactyls would require 27 pages in the book, given their diversity and taxo-nomic controversy. It is a bit confusing, however, that there are 10 pages devoted to the Entelodon-tidae (7 genera) and 21 to the Giraffidae (31 spe-cies, 3 extant) but only 8 to the Cervidae, the second most diverse family in the Artiodactyla and.

Even more surprising was that comparisons of these proteins used to determine evolutionary relationships often placed whales within the Artiodactyla as. The first three and last two chapters of the book present synthetic analyses of various aspects of the origin and evolution of artiodactyls and their evolutionary relationships with the cetaceans.

Beginning about 50 years ago the hypothesis of close phylogenetic relationships between artiodactyls – specifically hippos – and cetaceans gained.
