Hemithiris antarctica

No picture of Hemithiris antarctica 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 Hemithiris antarctica, or no answer at all. This entry cannot say which.

Time the record covers

At most 43 million years on record.

Every occurrence read is dated to somewhere between 66 Mya and 23.04 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

4 occurrences of Hemithiris antarctica 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

4 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.

26 taxa

The Paleobiology Database records 4 sites for Hemithiris antarctica, 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.

Entered from

2 references

Each of the 4 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. Each entry links to the Paleobiology Database's own record for the work.
