The Echinoid Directory

Family Galeritidae Gray, 1825, p. 428


Clade of Echinoneoida with:

  • ambulacral plating simple throughout; no pyrinoid plating;
  • periproct small, circular, positioned towards the posterior of the oral surface.
Cretaceous (Albian-Maastrichtian), Europe.

Differs from Conulidae by having entirely simple ambulacral plating. Echinoneidae also have strictly uniserial pore-pairs but have a large, oral periproct.

Echinogalerus has an oblique peristome with the long axis along amb. V - Iamb. 3 and ambulacra subpetaloid aborally, but has similar simple ambulacral plating.
