Tillodontia

Tillodontia is an extinct order or suborder of eutherian mammals known from the Early Paleocene to Late Eocene. They were most diverse and long-lasting in Asia, though several species also lived in North America from the Late Paleocene to Middle Eocene, and a few inhabited Europe during the Early Eocene. Leaving no descendants, their exact affinities are unclear. They may be most closely related to the pantodonts, another extinct group of early Paleogene herbivores. The tillodonts were medium- to large-sized animals that probably fed on roots and tubers in temperate to subtropical habitats.

Time the record covers

At least 13 million years on record.

The record covers at least 61.66 Mya to 48.07 Mya. No occurrence read is dated outside 66 Mya to 37.71 Mya.

448 occurrences of Tillodontia 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

448 occurrences

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 414 sites for Tillodontia, and this reads 240 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.

84 references

Each of the 448 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. 72 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
