Comment by Tom DeVries:

• Regarding info about Peruchilus - there is only Olsson's original study and my specimens from the Otuma Fm. of southern Peru (probably 38-36 Ma). That's all that is known. It probably lived in the inner to mid-shelf - not intertidally, not in slope-depth water.

Ectinochilus cf. gaudichaudi (d'Orbigny, 1842); late Eocene; Southern Peru; Coll. Tom DeVries; Copyright Tom DeVries
