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!
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!
