Possible survival of ammonites into the early Paleocene epoch
A fossil of Hoploscaphites, an ammonite believed to have survived the K-Pg extinction event well into the Paleocene
The term Paleocene ammonites describes families or genera of Ammonoidea that may have survived the Cretaceous–Paleogene extinction event, which occurred 66.043 million years ago. Although almost all evidence indicated that ammonites did not survive past the K–Pg boundary, there is some scattered evidence that some ammonites lived for a short period of time during the Paleocene epoch, although none survived the Danian (66-61 Ma);[1] they were likely extinct within 500,000 years of the K-Pg extinction event, which correlates to roughly 65.5 Ma.[1][2][3][4][5] The evidence for Paleocene ammonoids is rare and remains controversial.
