Globorotalia

Globorotalia is a genus of foraminifers belonging to the family Globorotaliidae. It is a single-celled protist large enough to be seen with a naked eye and is found in the fossil record back to the Paleocene. It is deep-dwelling planktonic foraminifers that inhabit the top few hundred meters of the ocean and constitute potential recorders of thermocline conditions. The genus has cosmopolitan distribution.

Time the record covers

At least 125 million years on record.

The record covers at least 125.77 Mya to 11.7 ka. No occurrence read is dated outside 132.6 Mya to 0 Mya.

12,000+ occurrences of Globorotalia on record. 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

12,000 occurrences read

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. The read hit its cap, so every figure above is a floor and the shares are of the occurrences read. More on what this infers.

The named rock units Globorotalia has been recovered from, largest first. Drawn where the rock is now, not where it formed. The read hit its cap, so each count is a floor. 22 further formations hold fewer occurrences each and are not listed. 11,901 occurrences have no formation on record, which is common for older literature.

Found in the same rock

1,655 taxa

The Paleobiology Database records at least 410 sites for Globorotalia, 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

at least 150 references

Each of the 12,000 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. That read hit its cap, so each count is a floor. 138 further references are not listed. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
