Hi all,
We were hiking at Arbor Hills in Plano, Texas, yesterday and found this little guy, along with another similar to it that I’ve posted below. Any help identifying is appreciated!
I also found this tiny little guy. I’m trying to reinvigorate my childhood obsession with all things geological, so excuse my ignorance. 2 questions: (1) what is this black clay at arbor hills called? And (2) is this tiny shell from a month ago or something older? I don’t know enough about the clay to make heads or tails of this.
