NEW YORK
PALEONTOLOGICAL SOCIETY
MEETING ANNOUNCEMENT

EVOLUTION, DEVELOPMENT, ECOLOGY

AND PHYSIOLOGY OF EXTINCT AMMONOIDS

Dr. Amane Tajika

JSPS Overseas Research Fellow

American Museum of Natural History

Sunday, May 19, 2019           2:00 P.M.            Room 319

American Museum of Natural History         New York City 

For more than 350 million years, the Ammonoidea were abundant in the world’s oceans. Until their demise in the K/Pg mass extinction event at the end of the Cretaceous, they were the most dominant cephalopod group in the marine realm. Their high abundance, geological longevity, high speciation rate, and world-wide distribution make them ideal model organisms to test evolutionary hypotheses, as well as offer key insights into the paleontological disciplines of biostratigraphy, biogeography and paleoecology. Extensive paleontological research has answered many questions about ammonoids, though many remain. This talk will address what we do know about these extinct organisms - including origins, ecological roles, habitat, locomotion, evolutionary trends, physiology and anatomy. Dr. Tajika will also discuss the differences between ammonoids and nautiloids, and explore why ammonoids became extinct while nautiloids survived the K/Pg mass extinction event, and will also identify the animals that exploited their ecological niche after the Cretaceous.
