A NEW VIEW OF THE DINOSAUR ASSEMBLAGES OF CHINA AND THEIR FUNDAMENTALLY COLD-ADAPTED ORIGINS Dr. Paul E. Olsen Storke Professor of Earth & Environmental Sciences Columbia University & AMNH Research Associate Lamont-Doherty Earth Observatory, Palisades, NY Sunday, February 16, 2025 2:00 P.M.
THIS MEETING WILL BE HELD ONLINE
Recent work by me and my colleagues over the past 19 years place the famous dinosaurs of China in a new, larger perspective in climate and evolution. Traditionally, attributed to Pompeii-like volcanic catastrophes, we have shown that the spectacular Late Jurassic and Early Cretaceous strata, with their flattened and 3D fauna, instead record normal life and death processes preserved in a succession of lacustrine and fluvial depositional environments. We show through phylogenetic bracket analysis, that dinosaurs are primitively cold adapted, and though exploration of the Junggar Basin of NW China, we show they lived in the arctic in the Late Triassic and Early Jurassic, which had freezing wintertime conditions despite very high atmospheric CO2. Together, China’s Late Triassic to Early Cretaceous dinosaur-bearing deposits show clear evidence of a massive true polar wander event. The whole shell of the Earth rotated with respect to its spin axis with East Asia translating south from the Arctic to the southern mid-latitudes and subtropics and back to mid-latitudes structuring the depositional environments that preserved those spectacular dinosaur assemblages, giving us a new perspective of their significance.
N.Y.P.S. MEETING DATES FOR THE YEAR These are the meeting dates of the New York Paleontological Society for the 2024-2025 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, due to policy changes and new construction, the Museum is unable to assign any rooms for meetings for any groups at this time. Exactly when the Museum will allow groups like our Society to reserve rooms is uncertain. 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:
