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!

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

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

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!

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

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

I want to give a special shoutout to those that donated to or advocated for childcare at the #JMIH25 meeting. Because childcare is available on site, I have been able to attend the meeting and present my research. It is a lifeline for early career researchers, particularly women!

Happy #FossilFriday from my lab space! Still working on the semionotiform death blocks, and I have finally set up my new scope!

While doing research for my Geology of the National Parks course, I came across this article by @tuttran.bsky.social on paleontology in Bryce Canyon National Park, which will always be my favorite NP. Spent so much time there with my family.

A big congratulations to my student Aimee Hruska, who graduated today with her M.S. in Biology from St. Cloud State. Hoping to get her research published this year!

Happy #FossilFriday! These are specimens of Receptaculites from the Ordovician Tyndall Limestone of Manitoba. These common Paleozoic marine fossils may look like coral, but it is still unclear what they are, most likely related to algae. From the SCSU Rock, Mineral, and Fossil Collection.

Howdy folks! The semester caught up with me, and I neglected my presence here. I have been spending free time cleaning up lab spaces and making progress! We have all of the SCSU Mineralogy collection in the same space now, ready to be organized and catalogued.

For #FossilFriday, I am spending time photographing this block, and once I got it in the right light, the surface really pops out with hundreds of tiny little Triassic fishes.

It’s exciting when a lab space becomes all your own but part of that is cleaning up the messes left behind, and not knowing how long it’s been that way.
