Tentaculita

Tentaculita is an extinct class of lophophorates ranging from the Early Ordovician to the Middle Jurassic. They were suspension feeders with a near worldwide distribution. For a more thorough discussion, see Tentaculites.

Time the record covers

At least 353 million years on record.

The record covers at least 505.3 Mya to 152.21 Mya. No occurrence read is dated outside 509.7 Mya to 149.2 Mya.

2,363 occurrences of Tentaculita on record, most of them in the Devonian. 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

2,363 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 at least 1,388 sites for Tentaculita, 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.

Entered from

365 references

Each of the 2,363 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. 353 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.
