Petsios Lab Paleobiology

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”.

@bibibivalve @ShamindriT Michal, I don't think you'll be able to hear the ocean in that one....

Paleodrama! Specimen of the Pliocene clam Astarte obliquata from the Netherlands escaped an almost certain death by a drilling snail 3(!) times. #FossilFriday #paleo #fossil #paleontology #snails adielklompmaker.com/images/stories…

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!

Pulses of sinking carbon are reaching the #deepsea in ways not captured by global #climate models: mbari.org/carbon-pulses-… @Mucktopus

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!

@bibibivalve We all come back to Turritella eventually

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

I'll also be at #GSA Indianapolis to meet with interested students and to talk about potential projects!

Interested in a degree in #invertebrate #paleontology? I'm looking for students (M.S. or Ph.D.) to work on large scale #macroecology or #macroevolution projects with me @BaylorGeo. Contact me or go to my website: sites.baylor.edu/elizabeth_pets…

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!
