Made a trip to Fort Gibson dam 4 days ago and saw these invertebrate fossils that looked to me like "spikey worms".  The ones in the photos are in rock and measure about 2 to 3 cm or more.  The road cuts are of Mississippian age on either side of the dam.  Also found a blastoid here.  What are the spikey worm fossils?

maybe "Archimedes' screws" (bryozoans)

Yup. Looks like Archimedes.

Fossil hunting is easy -- they don't run away when you shoot at them!
