Hippopharangites

Hippopharangites
Scientific classification
Kingdom:	Animalia
Phylum:	Mollusca
Family:	† Halkieriidae
Genus:	† Hippopharangites

Hippopharangites ^[1] has sclerites with a broad central cavity and small pores opening through the shell wall, equivalent to the lateral chambers of other halkieriids (and the aesthete canals of Chitons?) ^[2] As the animals grew, the shell plates grew by adding material to the outer edges. ^[3] This genus is the closest in form to Chancelloriid sclerites, and is thus used to support the union of halkieriids and chancelloriids as Coeloscleritophora. ^[4]
