Anthracomartidae

Anthracomartidae, first described by Haase, 1890, is a family of the extinct arachnid order Trigonotarbida. It is likely to be most closely related to the Archaeomartidae, based on a 2014 cladistic analysis, within the clade. Many specimens come from siderite nodules of late Carboniferous age in Europe and North America.

At least 37 million years on record.

The record covers at least 335.9 Mya to 298.9 Mya. No occurrence read is dated outside 339.9 Mya to 293.52 Mya.

64 occurrences of Anthracomartidae on record, most of them in the Carboniferous. 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

64 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.

32 references

Each of the 64 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. 20 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.
