This week’s Fossil Friday is a two-for-one! This single slab, found by Allan Lindoe in the Devonian Road River formation in the Northwest Territories, contains the remains of both Gladiobranchus (an acanthodian or “spiny shark”) and Aserotaspis (an agnathan, or jawless fish). This was one of the specimens that we got to examine during the Paleo 2026 workshop on early fish identification led by Dr. Jobbins and is UALVP47080.

#FossilFriday! 🐂 The first clue for me and my friend Bill that bison material could be found along the Cottonwood River’s gravel banks in southern MN.

In 2019, it hit 17.92 feet, with major crests on March 24 and April 19, high enough to reveal a few buried secrets.

This right frontal bone w/ horn core is from a juvenile bison. Other skull and horn core specimens have appeared since, but this was the first—and remains the only—juvenile skull we’ve found.

This week for #Fossilfriday we have another #Guess that #Lego #Fossil.

This one I would rate as easy. So easy you get no hints haha

Hide your guesses behind a content warning, so others can guess without being spoilt. I will post the answer tomorrow (and to anyone who guesses correctly).

The was designed by me.

#FossilFriday #MnMuseum highlight: Carver County Historical Society. Carver County’s past is on display, anchored by a mammoth molar amid exhibits on Indigenous history, agriculture, and military service.

The molar was found in 2000 at the W. Mueller & Sons gravel pit in Chaska, when Mori Willemsen’s clamshell dredge—dropping through 100 feet of water—hauled up a proboscidean tooth.

Here one of my favorite fossil #cephalopods for #FossilFriday:

Pentameroceras mirum from the #Silurian of #Gotland! Those narrow slits of the shell were likely where arms or eyes would stick out!
