Life in a Greenhouse: What Fossil Cephalopods Tell Us About Surviving on a Changing Earth Dr. Peg Yacobucci Professor, School of Earth, Environment & Society, Bowling Green State University Sunday, May 17, 2026 2:00 P.M.
THIS MEETING WILL BE HELD ONLINE Of all the mollusk groups in today’s oceans, cephalopods like octopuses, squid, and cuttlefish perhaps enjoy the most popularity, both because they are super-smart and engaging and (for some) because they are delicious! Indeed, global fisheries currently take in 4 to 5 million metric tons of cephalopods a year and they are an important protein source for many people. Besides their value to people, cephalopods are also critical members of marine food webs in all parts of the world’s oceans. Conservation biologists are understandably concerned about what will happen to cephalopods as human activities impact the world’s oceans over the next century. While most cephalopods today have no external shell, many ancient cephalopods had shells like modern nautiluses, producing a rich fossil record. In this talk, I will provide a brief overview of fossil cephalopods, especially the shelly nautiloids and ammonites, then share my lab’s work on how ammonites responded to episodes of greenhouse warming in the Cretaceous period. We have used a variety of methods—from quantifying form to reconstructing rates of evolution and extinction to modeling ammonite habitat suitability 94 million years—to better understand what made some ammonite groups more resilient than others in the face of rapid warming, reduced oxygen, and ocean acidification. Our results provide some predictions about what might happen to cephalopods in the future as our planet changes.
N.Y.P.S. MEETING DATES FOR THE YEAR These are the meeting dates of the New York Paleontological Society for the 2025-2026 season. We normally meet at 2:00 P.M. in a room at the American Museum of Natural History in New York City (79th Street and Central Park West). However, the Museum is unable to assign any rooms for our meetings at this time. However, as of this writing, we are now working with the Museum and some of its staff on obtaining rooms for at least some of our meetings this year (9/25- 5/26). Ideally, we will be able to meet in the Museum and online for the same meeting. But, since room availability may change, it has been decided to hold online meetings on the regular dates and times so that the schedule remains the same whether the meeting is in a room or online. One advantage of online meetings is that they will be recorded so members who can’t attend at the meeting time can view the whole meeting afterwards at their convenience.
Our Annual Party would normally be held at the NYU Tandon School of Engineering in Brooklyn, but new construction may effect the availability of a large enough venue space. Note, due to the nature of the party (many tables, events, talks and wonderful food), this event cannot be held online.
As of this writing, all of the dates this year are on the third Sunday of the month, except April’s. Also, our Annual Holidays Party would be held if possible on a Saturday (the date to be determined), but, again, the available venue space and rules may effect this event. The dates are as follows:
