The perfect echinoid this Valentine’s Day! They certainly have my heart!
Today is #WomenAndGirlsInScienceDay! Follow our amazing women faculty and graduate students: @PetsiosLab @rebreccia @kyrietree @elisabethrau @biolojenn @anna28559301 @Amanda96351758!
New preprint: How macroecology affects macroevolution: the interplay between extinction intensity and trait-dependent extinction in brachiopods biorxiv.org/content/early/…
Mark your calendars! Dr. Steve Driese will be giving a talk for Science Thursdays at the @MaybornMuseum on Thursday, January 31 from 7-8 pm (refreshments at 6:30 pm). His talk is titled “New Insights from Old Dirt”.
Prof. Dave Bottjer, honored by his former students, including @meclapham, with a special issue at Palaeo3 where he was an editor for sixteen years! doi.org/10.1016/j.pala… Holler by reply if you are a current or former Bottjer student on Twitter!

Most sea urchins have spines covered in a layer of tissue. Pencil urchins- Eucidaris tribuloides shown here- don't. That means the spines serve as a hard substrate for other inverts (barnacles, serpulid worms, bryozoans, hydroids, etc) to settle on. A traveling habitat! #1001jars
It was a good weekend for some Late #Paleozoic field work with @echinerd and @Andrew_G_Flynn with some amazing partially articulated #crinoids!
Jeff Thompson @echinerd giving an exciting #Paleozoic #echinoid talk tonight at the @dallas_paleo monthly meeting!
Caught spikey-handed? "When your oral surface is caught in the cookie jar..." Cidaroid urchin predation ("constant nibbling") on a black coral: an unusual behavior (?) #Okeanos, ~400m, Isla de Mona escarpment, Puerto Rico
Giving a talk tomorrow late afternoon (2:45 pm) at #GSA2018! Come see some really cool deep-time marine food webs 🦑🦞🐟🦐🦞🐡🦈
Great short course about teaching in paleontology today! Organized by members of the Paleontological Society. #GSA2018 #paleobiology #paleontology
TOMORROW BAWG will be hosting another HIS/HER Story Panel at 3:45 pm in BSB D410. Join us as Dr. Stacy Atchley, Dr. Steve Driese, Dr. Bill Hockaday, and Dr. Liz Petsios (@PetsiosLab) tell their stories. There will be ice cream!
@PetsiosLab On Friday Dr. Mary Schweitzer will be visiting from @NCState for GEO 5050: “Molecules in the Rock Record”. Refreshments at 2:30 pm, talk at 3 pm.
