Neobrachytherium
Neobrachytherium is an extinct genus of proterotheriid mammal from the Late Miocene of Argentina and Uruguay. It is represented by multiple species, including the type N. intermedium, originally named in 1891 by Moreno and Mercerat as a species of Licaphrium, N. morenoi, originally named in 1914 by Rovereto as a species of Brachytherium, and N. ameghinoi and N. ullumense, named in 2001 by Soria, who reclassified all the species in the new genus Neobrachytherium. The various species are known from cranial and dental material from the Corral Quemado, Loma de las Tapias and Ituzaingó Formations. Neobrachytherium may be closely related to Thoatherium, Diadiaphorus and Thoatheriopsis.

Time the record covers
At least 754 thousand years on record.
The record covers at least 8 Mya to 7.246 Mya. No occurrence read is dated outside 11.63 Mya to 3.6 Mya.
11 occurrences of Neobrachytherium on record, most of them in the Miocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
11 occurrencesThese are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 10 sites for Neobrachytherium, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
