Lima (Plagiostoma) subcardiiformis

Lima subcardiiformis Greppin, 1867, a relative of Lima (Plagiostoma) subcardiiformis — not Lima (Plagiostoma) subcardiiformis itself

Not Lima (Plagiostoma) subcardiiformis. This is Lima subcardiiformis Greppin, 1867, a relative — both are Limidae.

Time the record covers

At most 14 million years on record.

Every occurrence read is dated to somewhere between 174.7 Mya and 161.5 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

44 occurrences of Lima (Plagiostoma) subcardiiformis on record, most of them in the Middle Jurassic. 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

44 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.

382 taxa

The Paleobiology Database records 42 sites for Lima (Plagiostoma) subcardiiformis, 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.

Entered from

8 references

Each of the 44 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. 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.
