What type of animals are members of the proboscidean order?
Proboscideans are an order of eutherian mammals that include the living elephants as well as the extinct mammoths, mastodons and gomphotheres. All members of the order have a proboscis or trunk that they use to grab food and water.
Why is an elephant a Proboscidea?
Proboscidea—Elephant Relatives The head is large relative to the body in most; this is accomplished by having a large number of sinuses allowing large size without concomitant weight. Presumably the increased size forms surfaces for muscle attachments necessary to support the heavy tusks.
What did Moeritherium look like?
It was about as large as a tapir. It had short, strong legs, a relatively long body, and a short tail. The feet of Moeritherium were broad and terminated in flat-hoofed toes. The skull and cheekbone were long, and the eyes were set very far forward.
What are the characteristics of Elephantidae?

Are hippos Proboscidea?
During the Miocene, proboscidean groups emigrated to most other continents, becoming a widespread and important group until the extinction of most species in the Pleistocene. Elephants are sometimes called pachyderms, a term that also applies to rhinos and hippos, and refers to their thick skin.
What was the largest Proboscidea?
Elephants, mammoths, and mastodons (Proboscidea) The largest known land mammal ever was a proboscidean called Palaeoloxodon namadicus which weighed about 22 t (24.3 short tons) and measured about 5.2 m (17.1 ft) tall at the shoulder.
What caused the Moeritherium to go extinct?
These animals were longer than Asian elephants. The reason why these animals went extinct was because of climate change and human interference (hunting).
What is the Moeritherium related to?
Moeritherium (“the beast from Lake Moeris”) is an extinct genus of primitive proboscideans. These prehistoric mammals are related to the elephant and, more distantly, sea cows and hyraxes. They lived during the Eocene epoch.
What is the meaning of Elephantidae?
Definition of Elephantidae : a family of bulky mammals (order Proboscidea) comprising the recent elephants and related extinct forms (such as the mammoths) that differ from these chiefly in respect to their dentition and in former classifications including also the mastodons.
How many species are Elephantidae?
The Elephantidae. There are two living relatives of this group, the Asian Elephant (Elephas maximus) and the larger African Savanna Elephant (Loxodonta africana). These two elephants are closely related to the extinct mammoths that once roamed the planet.

The Proboscidea ( / prɒbəˈsɪdiːə /, from the Greek προβοσκίς and the Latin proboscis) are a taxonomic order of afrotherian mammals containing one living family ( Elephantidae) and several extinct families.
