Is this lil sucker a trilobite? I found this rock just outside Santa Fe, NM. There's a bunch of medium-sized shells and also crinoid stems, coral and stuff in this rock. There was a crud load of fossils where I found this one, although the only one I've suspected as being a trilobite.
It's kinda hard to show it in this pic, but it's the thingy with ribs. I'm guessing the head got cut off or something. I read though, that the fossils of trilobites are often molted skeletons, and that heads were often missing because of this.
Flash seems to show better detail.
If this is a trilobite, would it be worth sending it to an expert 'excavator' to dig it out of the rock more?
