First issue

Due mostly to an overlooked homonym, all mapped records and most of the information for this species are wrong. (https://www.gbif.org/occurrence/gallery?taxon_key=8373817)

Chama striata Smith, 1817 is actually in the order Ostreida, family Gryphaeidae. It is an ICZN-suppressed synonym of Nannogyra virgula (Deshayes, 1831), a European Jurassic species.

Chama striata Emmons, 1858 is a Pliocene to Pleistocene actual Chama from the southeastern U.S. It was renamed Chama emmonsi Nicol, 1953 (with a subjective synonym Chama gardnerae Olsson & Harbison, 1953).

As all the mapped records are in the southeastern US, they are Chama emmonsi.

The images are three sets of labels for specimens from Natural Well, NC (misspelled Natural Wells on the original labels). Natural Well is a Pliocene locality (incorrectly thought to be Miocene from the mid-1800's to about 1970, with some sources still not up to date). The labels attribute the species name to Emmons, and Chama emmonsi is common at Natural Well.

Paleobiology Database has records of Emmons' species incorrectly "corrected" to Nannogyra virgula.


Second issue (https://www.gbif.org/species/9412085)

In the database, this species is attributed to Agassiz as Singuuriqia cristatus (Agassiz 1844), a Tertiary Fish, following paleobiology database, although the entry for just the genus Singuuriqia, a Cambrian priapulid, is correctly attributed (i.e. to Peel 2017)

Form paleodatabase: †Wetherellus cristatus Agassiz 1844 (ray-finned fish) Actinopteri - Scombriformes - Scombridae

Alternative combination: Singuuriqia cristatus Belongs to Wetherellus according to K. A. Monsch 2004 Sister taxa: Wetherellus brevior, Wetherellus longior Type specimen: BMNH 28498, a partial skeleton. Its type locality is London Clay, Isle of Sheppey, which is in a Ypresian marine claystone in the London Clay Formation of the United Kingdom. Ecology: nektonic omnivore Distribution: found only at London Clay, Isle of Sheppey

Agassiz actually attributed the species cristatus to Pachycephalus. The species was described by Casier (1966) as Wetherellus cristatus and it is reviewed by:

Monsch, K.A. Transactions of the Royal Society of Edinburgh: Earth Sciences, 95, 445–489, 2005 (for 2004) Revision of the scombroid fishes from the Cenozoic of England

Singuuriqia was proposed by Peel (2017) as a priapulid worm: Peel, J.S., 2017. Feeding behaviour of a new worm (Priapulida) from the Sirius Passet Lagerstätte (Cambrian series 2, stage 3) of North Greenland (Laurentia). Palaeontology 60, 795–805 (published online 21 July 2017)

The attribution of the name to Agassiz in association with cristatus in the paleobiology database appears to be a simple error, also taken up by mindat.org and GBIF.

In the first issue, GBIFs backone does currently not have the species Chama striata Emmons, 1858 registered (as it is not in paleobiology DB) so the records are automatically indexed to Chama striata Smith, 1817. The issue affects 30 records from 6 different publishers: https://www.gbif.org/occurrence/search?taxon_key=8373817 which should all be indexed as Chama striata Emmons, 1858 due to the explanation above.
