I found this in quaternary alluviums but near a spot with a confirmed vert fossil find. It looks to me like half a cloven toe, but the mineralization seems sketchy. What do you experts think? Could it be a trace, like mud-filled footprint or is it another pseudofossil!? Thanks for humoring me!
I'm curious if anyone recognizes these structures. Found in Denver Basin, near fossil wood deposits. Lattice like structures, almost like giant ommatidia. Maybe a seed? Ticks in blurry scale are mm. Host rock is almost creamy, like chert/opaque agate. Thank you!
