Chasicotherium rothi

Chasicotherium is an extinct genus of a large notoungulate mammal known originally from a partial skull and mandible discovered in the Arroyo Chasicó Formation, in the stream of Party of Villarino, Buenos Aires, Argentina. The sediments in which the animal was discovered dates to 10 to 9 million years (Chasicoan). It is known only from the type species, C. rothi. Its weight was approximately 1 tonne, being the largest and most recent member of the family Homalodotheriidae. It was a large herbivore of the Miocene Pampas, closely related to Homalodotherium, which also shares the reduced dental formula of the short premaxilla.

No picture of Chasicotherium rothi was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Chasicotherium rothi, or no answer at all. This entry cannot say which.

Time the record covers

At most 2 million years on record.

The one occurrence read is dated to somewhere between 10 Mya and 8 Mya, which is a dating window rather than a span.

1 occurrence of Chasicotherium rothi 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

1 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.
