Description
Notiomastodon platensis is known from MECN 82, a 35-year-old male that was 2.52 metres (8.3 ft) tall and weighed 4.4 tonnes (4.3 long tons; 4.9 short tons). 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. 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.
Taxonomy
Notiomastodon was named by Cabrera (1929). It is not extant. It was assigned to Gomphotheriidae by Carroll (1988).
