Anacostia

No picture of Anacostia was found. Wikidata was searched and had none. Wikipedia has a picture filed under this name, but nothing tied it to Anacostia itself, so it was not used. iDigBio and GBIF were not searched: the Paleobiology Database does not place Anacostia firmly enough to tell it from something else bearing the same name, and a search on the name alone returns whichever of them was photographed. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is.

Time the record covers

At most 43 million years on record.

Every occurrence read is dated to somewhere between 143.1 Mya and 100.5 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Anacostia on record, most of them in the Early 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.

Found in the same rock

1 taxon

The Paleobiology Database records 1 site for Anacostia, and this reads all of them. The number is how many of those sites it was catalogued from too.

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

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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
