Calcidiscus leptoporus

Calcidiscus leptoporus is a coccolithophore species found extensively globally both in the oceans and in the fossil record, which dates back to the Early Miocene. C. leptoporus, like all coccolithophores, is a unicellular marine phytoplankton within the phylum Haptophyta, which is surrounded by calcium carbonate plates called coccoliths.

4,585 occurrences of Calcidiscus leptoporus 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

4,585 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.

223 taxa

The Paleobiology Database records at least 2,000 sites for Calcidiscus leptoporus, 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

132 references

Each of the 4,585 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. 120 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.
