Although they look similar to clams ?
Prominent beaks can be found on the pedicle valve of the Kutorginida order in this phylum, while a very small number of Thecideida are still alive today from this phylum. The Lingula genus is unusual amongst them because it consisted of burrowing species, and they have historically been divided into Articulata and Inarticulata classes. Like Bryozoa and Phoronida, they possess a feeding organ known as a lophophore, and their abundance in the Paleozoic era make them the most common extant fossils. Although they look similar to clams ? because they all possess two shells, they are evolutionary divergent and are predominantly found in trenches or polar regions. FTP, identify this phylum, sometimes known as lamp shells.
