Discoscaphites is an extinct genus of ammonite. This genus may have been one of the few to have briefly survived the K-Pg mass extinction.

Distributions

Cretaceous of Greenland, Alabama, Arkansas, California, Colorado, Kansas, Maryland, Mississippi, Missouri, New Jersey, South Dakota, Tennessee, Texas, Wyoming,[1] and North Carolina.[2] Discoscaphites is present in the famous Pinna Layer of the Tinton Formation of New Jersey (above the iridium anomaly), with even possible records in the layer above, along with Eubaculites.[3] Some researchers prefer a conservative interpretation when dating the Pinna Layer, the other remains still suggest Discoscaphites was a K-Pg survivor, albeit restricted to 65 Ma.[4]
