Collected this a few years ago on the bank of Trinity river near the surface. There was a layer of sorts of this and that's where this concretion was containing a little Baculite poking out. So I'm assuming this is result of some evaporate process and this is gypsum but how did it come about? Was the concretion sitting in shallow muddy water? Hoping someone can explain the process that produced this.
