Discovering Plesiobaena: An Ancient Cretaceous Turtle

Large calcareous concretion #shorts

This is an extremely rare and crystallized fossil Ammonite within a Golden Calcite Concretion from Utah. Unlike a classic Geode, Concretions form around a centralized object typically of organic matter such as a bone, shell, or organic debris. Mineral-rich fluids begin to precipitate around this central nucleus creating layers of harder more weather-resistant mineralization. On the rare occasion Ammonite fossils are discovered in Concretions, their growth chambers are always completely infilled

A concretion. Formed in the sedimentary layers that make up the Cliffs millions of years ago.
