It is a widespread and diverse genus, currently containing 10 species. They are uncommon but present throughout the late cretaceous of the eastern United States, including the Severn Formation of Maryland, the Tar Heel and Peedee formations of North Carolina, and Campanian of New Jersey. It is also known from the Western Interior Seaway and western Europe. C. hashimiaensis is known from the Santonian of Jordan. C. alhaulfi is from the Barremian.^[2][3]
