Notiomastodon is an extinct genus of proboscidean[1] endemic to South America[2] during the Pleistocene from 1.810 Ma—780,000 years ago, living for approximately 1.019 million years.[3]

Notiomastodon platensis is known from MECN 82, a 35-year-old male that was 252 centimetres (99 in) tall and weighed 4.4 tonnes (4.3 long tons; 4.9 short tons).[4] It had two tusks on either side of a trunk like other members of Gomphotheriidae. Its apparent range was the central to southern continent with fossils recovered in Tarija Province, Bolivia.[5] It would have probably shared its habitat with Haplomastodon based on genus age of existence and geography.

Paleobiology

Their diet consisted mainly of C3 and C4 grass.[6]

Taxonomy

Notiomastodon was named by Cabrera (1929). It is not extant. It was assigned to Gomphotheriidae by Carroll (1988).
