Hey! We did a thing!

For #FossilFriday have a look at the holotype of †𝘾𝙖𝙧𝙡𝙤𝙢𝙤𝙣𝙣𝙞𝙪𝙨 𝙘𝙖𝙧𝙣𝙚𝙫𝙖𝙡𝙚𝙞 sp. nov., from the Eocene of Monte Bolca, Italy. Read the full study by Reichenbacher 𝘦𝘵 𝘢𝘭. (2025): buff.ly/3iDP5Vl #PaleoSky #FossilFish

Plans for the Lyme Regis Fossil Festival 2026 are now online, and it's going to be an outstanding event. I'm one of many speakers (I'm also doing a book signing and other stuff too). This year's event is June 13-14, go to.... fossilfestival.com

Anything that promotes more rocks in your landscaping is fine by me!

St. Cloud State Today did a nice write-up about my student Eryn's research of flood preparedness in Upper Midwest state parks and recreation areas. @stcloudstate.bsky.social

New paper out in JSP! Cooper & Maxwell present a redescription of 𝙎𝙖𝙪𝙧𝙤𝙥𝙨𝙞𝙨 𝙡𝙤𝙣𝙜𝙞𝙢𝙖𝙣𝙖 Agassiz, 1843 from the Upper Jurassic Solnhofen Archipelago (Tithonian, Germany) and the taxonomic diversity of 𝙎𝙖𝙪𝙧𝙤𝙥𝙨𝙞𝙨 Agassiz, 1832 (Actinopterygii: Pachycormidae). Read here: buff.ly/uGXjDLA #PaleoSky

A zombie cardinal in my yard this evening. His right eye looked completely normal. Poor fella just has some unfortunate molting issues I hope.

Ichnology appreciation continues in my children. This time it’s my daughter’s turn to examine deer tracks in fresh snow.

Very proud of my student Eryn Bloom, who presented her research at the Posters at St. Paul (P@SP) event in the Capitol Rotunda. She won a Distinguished Poster Award for presenting her work on Flood Risk Preparedness in campgrounds of the Upper Midwest. @stcloudstate.bsky.social

Nothing like Scapanorhynchus! Goblin sharks were coastal sharks in the Cretaceous in the Western Interior US and survive as deep water sharks today. @jeremybroberts.bsky.social @utahpaleo-ufop.bsky.social @paleontologizing.bsky.social @sharkscience.bsky.social Save Lebanon & Palestinians.

Velociraptors are funny because people are like "They weren't actually that scary because in real life, they were about the size of a goose" and my friend, have you ever been AROUND a goose? That just makes it worse!

Hans Sues was a phenomenal paleontologist, and a kind person. It is nice to have known someone like him in the field. For those of you who didn't know him, enjoy listening to him talk dinosaur facts. He was a good one and will be genuinely missed.

The Paleontological Society statement on recent events.

Thank you to @csdfacility.bsky.social for their support and assistance today as we processed four lake sediment cores for Drew O.’s senior research! Excited to see what we can learn about sedimentation in Ann Lake!

Spent the day at the CSD lab at the University of Minnesota processing lake cores from near Sand Dunes State Forest. Was a great opportunity to learn some new techniques!

My 5-year-old is a budding ichnologist. He was very proud of finding and examining this fresh squirrel trackway on the way to the bus stop this morning.

It’s an honor to be featured among so many great female paleoichthyologists! www.researchgate.net/publication/...

This was actually a great listen about the now viral Coalie and his less-nefarious origins.

This is a #mom appreciation thread: I have fond memories of watching the #Olympics with my mom, who was the biggest fan I knew. She was an amazing role model, dedicating much of her life to service and volunteering. She celebrated diversity and cultures, and I love that she gave that to me....

My Field Geology class’s field season is over, so here they are mapping out major geologic events and their respective field sites on a 100-foot geologic time scale. Putting things into context!

Tree space and a new ray-finned fish out today! We delve into how methods to visualize the forest of phylogenetic tree space can be used to address the rogue taxon problem. Shout out to my co-authors and advisors Michelle Stocker and Michael Gottfried. ssbbulletin.org/index.php/bs...

A great day of talks on the second day of the MN Association of Floodplain Managers conference. Excited to bring some new ideas to the classroom. @stcloudstate.bsky.social

A great first day at the Minnesota Association of Floodplain Managers conference. Some of our @stcloudstate.bsky.social students were able to visit important sites along the Mississippi River as part of the conference field trip. #mnafpm

My latest for @nytimes.com! For 40 years, paleontologists have grappled over whether a small tyrannosaur — named Nanotyrannus — was its own animal, or simply a teenage T.rex. The debate has been ... contentious. Which is why it's so fun to finally be able to say this: Folks? Nanotyrannus is real.

SVP President @stuartsumida.bsky.social speaks to Open Access Government about the importance of vertebrate paleontology and science in the United States. www.openaccessgovernment.org/the-importan...

A phenomenal paleontologist and a pleasure to talk to at SVP conferences. Mark will be missed.

Excavated from the Pisces Point locality of Scollard Formation in Alberta, Canada, ~67 million years old, Acronichthys maccognoi, newly reported in @science.org, was recovered from ancient water body that flipped seasonally between fast-flowing channels and quiet, still pools.

It’s time for my biennial reminder that I love where I live and that I can access this any time I want, and that I need to vist more often. #fieldgeology #quarrypark

The student of a friend would like input on the public perception of paleontologists (from non-paleontologists) for an assign. So help a student out, would you please? :) docs.google.com/forms/d/e/1F...

Visiting an active quarry is absolutely fascinating! I think the Field Geology class enjoyed it as well. Thank you to Martin Marietta St. Cloud Quarry @martinmariettam.bsky.social for the opportunity!

The 2026 MESTA conference program is coming together! With keynote speaker Danielle Heffernan, sessions on hydrology, astronomy, & geology, and networking opportunities for Minnesota Earth Science teachers, it's sure to be a great time. Register now at www.mnearthscience.org

Team SCSU fishes!! today.stcloudstate.edu/2025/09/18/s...

Look again! This isn't a close up of a planet. Definitely not Jupiter. This is a thin section of shale under a microscope (4x magnification). 😊 #STEMphotography #SciArt

Come visit me today at the Science Museum of Minnesota’s annual DinoFest! I’ll have fish fossils and Donnie the Dimetrodon with me and ready to talk about all things fossiliferous! Smm.org

Speaking of Brian Engh, I interviewed him years ago for PLOS Blogs, and have archived those posts on my personal website. They might be a bit outdated (I just updated them a bit) but check them out and give him some deserved love: sarahzgibson.com/2017/04/12/p...

The research lab space continues to get upgraded. Finally got my Brian Engh art prints hung up! Depictions of the Kayenta Fm (Sarah’s Fish Bed), Aquilops, and the Chinle Fm (featuring several fishies I described!). Brian’s a great paleoartist, check out his work: www.livingrelicproductions.com
