It's too damn hot for a penguin to be just walkin' around here.

I'm pretty curious what those black dendritic markings are. I borrowed a book on fossils from the library and I've been seeing a lot of similar markings on photos of ammonite fossils but I'm still leaning toward the larger fossil being something in the plant kingdom, though I could also see it being crustaceans or a trilobite of some sort.

I'm pretty sure the black dendritic markings is just desert varnish, manganese oxide.

No idea what the fossil is.
