like fossil sharks, there are literally bazillions of fossil shark teeth from various ages available to the market, yet there are few whole shark skeletons
1sharks renew their teeth
2teeth are more durable and fossilize more easily than a skeleton.
Id imagine the same is true for lots pf other animals includdeing spinosaurs.
Since spinosaurs are unoique age-wise and geographically, Id ask whether my spinosaur teeth are (I believe)moroccan and are from the cenomanian age.
