lamellipanssaria
Lamellipanssaria is a genus of extinct marine invertebrates belonging to the class Echinoidea. These organisms are characterized by their flattened, disc-shaped tests, which are often preserved as fossils. The name "lamellipanssaria" is derived from Latin and Greek roots, referring to the lamellar or plate-like structure of their test and their panssarian (or possibly related to their broad, flat shape). They are known primarily from fossil evidence, with their soft tissues not typically preserved.
Fossil specimens of Lamellipanssaria are found in marine sedimentary rocks dating back to the Mesozoic Era.
The classification of Lamellipanssaria within the broader scope of echinoid evolution is an area of ongoing
