Heterocyathus aequicostatus
Heterocyathus aequicostatus is a small species of coral in the family Caryophylliidae in the order Scleractinia, the stony corals. It is native to the Indo-Pacific region. It is a large polyp, solitary, free-living coral and is usually found on soft substrates.

Time the record covers
At least 5.2 million years on record.
The record covers at least 5.333 Mya to 129 ka. No occurrence read is dated outside 11.63 Mya to 0 Mya.
22 occurrences of Heterocyathus aequicostatus on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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
22 occurrences- Miocene5%
- Pliocene37%
- Pleistocene59%
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 9 sites for Heterocyathus aequicostatus, 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.
