Hey guys, I was wondering if ya'll could help me identify these. All were found in Texas to the best of my knowledge. I have what I believe to be the phyla of each but I'm not totally sure so take it with a grain of salt.

Photo 2: Hemichordata
Photo 3: Bryozoa
Photo 4: Chordata, this is obviously a shark tooth I think but I'm unsure of the species
