Telmatheriina
Telmatheres were a group of derived (advanced) brontotheres. Telmatheres were medium-sized to large brontotheres, found in Middle Eocene deposits in North America and East Asia. Telmatheres were close relatives of the horned brontotheres, and include the largest known brontotheres without horns. It is unclear if the telmatheres form a monophyletic group, since the positions of some genera vary between phylogenetic analyses.

Time the record covers
At least 2.7 million years on record.
The record covers at least 39.7 Mya to 37 Mya. No occurrence read is dated outside 56 Mya to 33.9 Mya.
5 occurrences of Telmatheriina on record, most of them in the Eocene. 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
5 occurrences- Eocene100%
These 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 5 sites for Telmatheriina, 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.
