Burmesarchaea grimaldii

Burmesarchaea is a diverse extinct genus of spiders, placed in the family Archaeidae. The type species Burmesarchaea grimaldii was first described in 2003 and least 13 more species have been assigned to the genus. The genus has been exclusively found in Cretaceous Burmese amber, which is dated to 99 million years ago.

No picture of Burmesarchaea grimaldii was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Burmesarchaea grimaldii, or no answer at all. This entry cannot say which.

Time the record covers

At most 6.6 million years on record.

Every occurrence read is dated to somewhere between 100.5 Mya and 93.9 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Burmesarchaea grimaldii on record, most of them in the Late Cretaceous. 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 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.

2 references

Each of the 2 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.
