I’m not sure what species or group these dinosaur teeth are from, first one seems to me to be either Tyrannosaurid or Dromeosauird. I’m learning towards Dromeosaurid but I’m obviously no expert.The tooth measures 1/4 inch x3/16 and is from Garfield county Montana. Second tooth correct me if I’m wrong but doesn’t seem to be Tyrannosaurid nor Dromeosaurid. It has a weird shape and I’m not sure what group of dinosaur it’s from. It’s also from Garfield county, Montana. And measures half an inch x1/16. Sorry about image quality
