The Dallas Paleontological Society was founded in 1984 for the purpose of promoting interest in and knowledge of the science of paleontology. It was intended by the founding members that the Society would be a network for the exchange of data between professionals and serious amateurs in this field.
June 9 Meeting was held on ZOOM
Our June meeting was on Wednesday, June 9th. We started the online meeting on Zoom at 6:30pm Central Time with informal chat and show-and-tell of fossils, and the formal meeting started at 7:00pm. Dr. Sean Gulick, Research Professor at the Institute for Geophysics and the Department of Geological Sciences at UT Austin, spoke on “Life and Death by Impact: Drilling for Clues.”
Here is a short abstract of his talk: The most recent of Earth’s five largest mass extinction events occurred 66 million years ago, coeval with the impact of a ~12 km asteroid, striking at ~60 degrees into what is today the Yucatán Peninsula, México, producing the ~200 km-wide Chicxulub crater. This impact, by some estimations, drove the extinction of 75% of life on Earth at the genus level including all non-avian dinosaurs. Proposed kill mechanisms include thermal effects caused by the reentry of fast ejecta into Earth’s atmosphere, dust, soot, and sulfate aerosols reducing Earth’s solar insolation and ocean acidification. In 2016, 835 m of core was recovered from the Chicxulub impact structure through IODP-ICDP Expedition 364. Analyses done on these cores, downhole logs, and geophysical site survey data have led to a series of advancements to our understanding of impact cratering processes and to how the Chicxulub impact affected the Earth’s environment leading to the Cretaceous-Paleogene mass extinction. Key areas of discovery include: (1) clear evidence for origin of peak rings and crater dynamics in large impacts, (2) highest resolution record to date of impact processes within the crater include deposition of impactites and role of ocean resurge, (3) rapid recovery of life at ground zero with a key niche being filled by cyanobacteria, and 4) development of a long lived hydrothermal system with astrobiological implications.
See you in July, second Wednesday of the month, for our next meeting
Dallas Library and DPS
The Dallas Library’s Podcast on Natural Dallas (P.O.N.D.) Annual Community Nature Expo includes a video featuring the DPS. Please watch all the videos for some interesting things to do and learn about in the outside world. Visit http://dallaslibrary2.org/pond/ for the videos.
Fossil Bits and Pieces
We at SMU prepared a short video about the Smithsonian exhibit, "Sea Monsters Unearthed: Life in Angola's Ancient Seas," that has been posted on the Embassy of Angola in the United States website (https://angola.org) and on the Embassy Facebook page. To see it, click on the link (https://angola.org), which will take you to the website. The video is playing without sound on the banner. Scroll down to Highlights and you will see a photo of a fossil. Click on that photo and you will see the video with sound and Portuguese captioning on the Embassy Facebook page. Attached is an information sheet about the exhibit, prepared for the Angolan Embassy. If you would like the video with English captioning, just let me know. Enjoy!

The PIT Crew
The Paleontologists In Training is a program of the DPS that is open to kids from age 7 to 15. If you are interested in fossils, want to have fun on field trips, and like learning about our beautiful world, come join us at one of our meetings, or field trips. You will find it educational, and fun at the same time!
