Echinoidea

Searched as Echinus. The Paleobiology Database treats Echinoidea as the accepted name.

Echinus is a genus of sea urchins. Sea urchins are echinoderms that are typically spherical or flattened with a covering of spine-like structures. Sea urchins tend to be important members of their ecosystems by grazing on other organisms and stabilizing populations. In addition to this, sea urchins play a large role in different economies globally as the urchin themselves and their roe are sold for consumption. The same is true for the species within the genus Echinus.

Time the record covers

At least 458 million years on record.

The record covers at least 458.2 Mya to 11.7 ka. No occurrence read is dated outside 471.3 Mya to 0 Mya.

11,656 occurrences of Echinoidea on record, most of them in the Late Cretaceous. 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

11,656 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 named rock units Echinoidea has been recovered from, largest first. Drawn where the rock is now, not where it formed. 1,227 further formations hold fewer occurrences each and are not listed. 3,481 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records at least 945 sites for Echinoidea, 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.

1,378 references

Each of the 11,656 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. 1,366 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.
