Stegotetrabelodon emiratus

Stegotetrabelodon emiratus is an extinct elephantid known from the Late Miocene Baynunah Formation of the United Arab Emirates, on the Arabian Peninsula, where its fossils date to roughly 8 to 6 million years ago. It is the earliest known species of its genus, and the genus is the most primitive group in the elephant family, keeping permanent premolars and long lower tusks that were the longest known in any proboscidean. A size estimate for this species gives about 3.7 metres at the shoulder and 10 to 11 tonnes in weight. Footprint tracks in the same part of the United Arab Emirates, thought to have been made by Stegotetrabelodon, indicate that these animals lived in herds.
