Mixed Cretaceous shark teeth from Dallas Texas

I’m very excited by the most recent addition to my shark tooth collection, this chunk of Cretaceous matrix from the Cretaceous deposits around Dallas, Texas. I can see at least 17 squalicorax teeth, 6 Ptychodus teeth and two other unidentified species, plus several other root lobes protruding our, undoubtedly still attached to the blades that are buried within the rock. There are also a few bits of bone scattered throughout. I wonder how so many teeth of so many species could gather and fossilize together in such a way.
