Altusmirus triquetrus

Altusmirus is an extinct genus of ground shark from the Early Cretaceous age of Austria. There is only one known species, A. triquetrus, named by Iris Fuchs in 2018. It was related to Fornicatus.

No picture of Altusmirus triquetrus 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 Altusmirus triquetrus, or no answer at all. This entry cannot say which.

Time the record covers

At most 4.5 million years on record.

The one occurrence read is dated to somewhere between 137.05 Mya and 132.6 Mya, which is a dating window rather than a span.

1 occurrence of Altusmirus triquetrus on record, most of them in the Early Cretaceous. 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.

The Paleobiology Database records 1 site for Altusmirus triquetrus, and this reads all of them. The number is how many of those sites it was catalogued from too.

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.
