Ammonite Fauna and Short-Term Survival Across the K-Pg Boundary From a New Site in the Us Gulf Coastal Plain

Supplemental Material: Ammonoid extinction vs. nautiloid survival: Is metabolism responsible?

“…Eubaculites carinatus in the U.S. Gulf Coastal Plain; Naujokaityte et al 2021) This species exhibits approximately the same metabolic rate as other ammonoids. Thus, there is no clear link between metabolic rate and short-term survival of ammonoids.…”
