7 years, 4 months ago7 years, 4 months agoTetraodontidae: Having four teeth
Tetraodontidae is the family of pufferfish. This family is aptly named for the four fused teeth plates that these fish use to crush mollusks. Because teeth preserve so well, the teeth plates of long dead specimens can be found in fossil beds like at Montbrook. @catherine-mueller found this beautiful spe…[Read more]

Jeanette Pirlo started the topic Crushing Power in the forum K-12 Fossils and Lessons Forum 7 years, 5 months ago
7 years, 5 months ago7 years, 5 months agoRay skeletons, like sharks, are made out of cartilage and are very difficult to preserve. Luckily, like sharks, rays also have a conveyor-like system for their dental plates, and replace them often throughout their lifetimes. K-12 teachers @maggie-paxson, @catherine-mueller, and Brett Stubbs discovered 2 different ray plates while at Montbrook.…[Read more]
