Současný pohled na evoluci chobotnatců Současná systematika chobotnatců není kompletně odvozena od jejich fylogeneze, rekonstruované pomocí kladistických metod. Diskutované skupiny tak mnohdy nepředstavují monofyletické skupiny. Přestože jsou taxonomické kategorie matoucí (např. Laurin 2005), jsem do jisté míry nucen je používat. Některým skupinám úrovně stále přiřazeny nebyly a zde této skutečnosti není přisuzován žádný význam. V této rešerši jsem se zaměřil hlavně na poznatky, které následovaly po vydání knihy; The Proboscidea: Evolution and Paleoecology of Elephants and Their Relatives, od Shoshaniho a Tassyho (1996). Chobotnatci jsou součástí skupiny Tethytheria společně s anthracobunidy, sirénami a desmostylidy (Shoshani 1998; Shoshani & Tassy 1996; 2005; Gheerbrant & Tassy 2009). Základní klasifikace sestává ze dvou skupin. Ze skupiny Plesielephantiformes, do které patří čeledě Numidotheriidae, Barytheriidae a Deinotheridae a ze skupiny Elephantiformes, do které patří čeledě Palaeomastodontidae, Phiomiidae, Mammutida, Gomphotheriidae, tetralofodontní gomfotéria, Stegodontidae a Elephantidae (Shoshani & Marchant 2001; Shoshani & Tassy 2005; Gheerbrant & Tassy 2009). -

The Distribution of Proboscidea (Elephants) Professor Dr
The Distribution of Proboscidea (Elephants) Professor Dr. Erich Thenius [In: Kosmos #5, May, pp. 235-242, 1964, Stuttgart] When I speak here about animals with a trunk, I do not mean the tapirs or pigs, but I refer only to the elephants and their ancestors, like the Mastodons and Dinotheria which we call the Proboscidea (after the Greek: proboscis = trunk). Their main characteristic is their remarkable trunk which has been fashioned to become a “gripping” organ. That organ was not present in the geologically oldest ancestors whose skeletons stem from the deposits of the Eocene (old Tertiary) in Africa. Even though we have no “soft tissues” of those animals, their skeletal features suffice to tell the scientist just what their bodily characteristics would have been. Thus also, we are not really going to discuss much about their distribution in historic times, but rather, we will concentrate on the development of these characteristic mammals, from their inception to their distribution in the past. A history of the Proboscidea is necessarily a history of their distribution in time and space. Information of these animals is available from numerous fossil findings in nearly all continents. But, before we even consider the fossil history, let us take a quick look of the current distribution of elephants which is shown in Figure 1. Nowadays, there are only two species of elephants: the Indian and African elephants. They not only differ geographically but also morphologically. That is to say, they are different in their bodily form and in their anatomy in several characteristics as every attentive zoo visitor who sees them side-by-side easily observes: The small-eared Indian elephant (Elephas maximus) has a markedly bowed upper skull; the African cousin (Loxodonta africana) has longer legs and markedly larger ears. -

From the gigantic mammoth to the massive mastodon, these creatures have captured the world’s fascination. Meet “Lyuba,” the best-preserved baby mammoth in the world, and discover all that we’ve learned from her. Journey back to the Ice Age through monumental video installations, roam among saber-toothed cats and giant bears, and wonder over some of the oldest human artifacts in existence. Hands-on exciting interactive displays reveal the difference between a mammoth and a mastodon, This sketch shows a Columbian mammoth, an offer what may have caused their extinction, and show African elephant, and an American mastodon how today’s scientists excavate, analyze, and learn more (from back to front). -
Paleobiogeography of Trilophodont Gomphotheres (Mammalia: Proboscidea)

We have attempted to interpret the biogeographical history of trilophodont gomphotheres in the context of the geological evolution of the continents they inhabited during the Cenozoic. To reconstruct this biogeographic history we used DIVA 1.1. This application resulted in an exact solution requiring three vicariant events, and 15 dispersal events, most of them (i.e., 14) occurring at terminal taxa. The single dispersal event at an internal node affected the common ancestor to Sinomastodon plus the clade Cuvieronius – Stegomastodon. A vicariant event took place which resulted in two isolated groups: (1) Amebelodontinae (Africa – Europe – Asia) and (2) Gomphotheriinae (North America). The Amebelodontinae clade was split by a second vicariant event into Archaeobelodon (Africa and Europe), and the ancestors of the remaining genera of the clade (Asia). In contrast, the Gomphotheriinae clade evolved mainly in North America. -
Backgrounder
BACKGROUNDER Mammoths: Giants of the Ice Age Exhibition Walk Through Mammoths: Giants of the Ice Age will transport people back to a time great beasts dominated the world and ancient peoples struggled to survive in a rapidly changing environment. During the Ice Age, mammoths would have existed right here in British Columbia. The Royal BC Museum’s refreshed Natural History gallery, opening at the same time as the feature exhibition, will help tell this story, linking the rise and decline of mammoths around the world to mammoths here in BC. The exhibition gives visitors unique opportunities to: Discover Mammoth and Mastodon Origins and Evolutionary Adaptations The family tree of elephants, mammoths, and mastodons can be traced back 55 million years when the proboscidean (pronounced pro-bo-SID-e-an) order originated in Africa. Trunks and tusks are the hallmark of proboscideans. In the first section of the exhibition, visitors encounter a full-size model of Moeritherium (Mer-i-THER-ee-um), an ancient cousin of mammoths, mastodons and elephants, displayed as it might have looked grazing in a North African wetland some 35 million years ago. Surprisingly, Moeritherium did not resemble its later cousins – it was somewhat larger than a modern- day tapir, but with short legs, a relatively long body, and a short tail. This introductory section also features a proboscidean family tree with touchable scale models of family members, including a woolly mammoth, a Columbian mammoth, and an American mastodon. The family tree illustrates how mastodons split off, forming the Mammutidae family – now extinct – while mammoths and elephants are part of the Elephantidae family. -

Early Elephant 'Was Amphibious' 15 April 2008
Early elephant 'was amphibious' 15 April 2008 Alex Liu, with colleagues Erik Seiffert from Stony Brook University (USA) and Elwyn Simons from the Duke Lemur Center (USA), analysed the oxygen and carbon isotope ratios contained within tooth enamel from both extinct proboscideans. While carbon isotopes can give clues as to an animal’s diet, oxygen isotopes found in teeth come from local water sources - and variations in the ratios of these isotopes can indicate the type of environment the animal lived in. They compared the ratios of these isotopes to definitely terrestrial animals from the same period and these results – Moeritherium - an early elephant which we now know when combined with results from studies of had an amphibious hippo-like lifestyle.

Mammoths and Mastodons Exhibition Walk Through
Exhibition Walk-Through Mammoths and Mastodons: Titans of the Ice Age takes visitors on a journey back to the time when these huge creatures roamed the Earth. The exhibition gives visitors unique opportunities to: Discover Mammoth and Mastodon Origins and Evolutionary Adaptations The family tree of elephants, mammoths, and mastodons can be traced back 55 million years when the proboscidean order originated in Africa. Trunks and tusks are the hallmark of proboscideans (pronounced pro-bo-SID-e-ans).

The family tree illustrates how mastodons split off, forming the Mammutidae family – now extinct – while mammoths and elephants are part of the Elephantidae family. Visitors can examine skull casts and fossil jaws, teeth and tusks to learn more about early evolutionary adaptations. Hands-on interactive displays teach visitors about two distinctive features of proboscideans: trunks and tusks. Visitors can try their hand at picking up objects by manipulating a mechanical trunk. In another interactive, visitors can help a mammoth balance the weight of its tusks. -
