I found these that resembles burrow or root cast in Ellsworth county, Kansas, USA from my previous trip. The formation these came from are most likely Kiowa formation/Kiowa Shale and the age is Albian. Here's the link to my previous trip. I'm just catching up with the prepping and sorting my fossils from my previous trips. I am wondering if it is some sort of ichnofossils. Is it burrow, root cast, or something else? Also, is it possible for it to be from geological origin rather than a true ichnofossil? This one is the largest I found. The center is poorly cemented sandstone and can be easily brushed off with a toothbrush while the outside layer is hard. Notice the winkles around the interior bend. The measurement is in inches (I know I need to get a metric system badly, my apologies!)
