Macluritidae

Macluritidae is an extinct family of relatively large, Lower Ordovician to Devonian, macluritacean gastropods(?), hypserstrophically coiled, that is dextral while appearing sinsitral, of which the genus Maclurites is arch-typical. The base of their shells is flat or gently protruding while the upper side is generally concave.

Taxonomy

J.B Knight, et al., 1960[2] included the Macluritidae in the prosobranch Archeogastropoda and included the family in the Macluritacea. Linsely and Keir, 1984[3] removed the Macluritidae, along with the Onychochilidae, to the Paragastropoda, a new class of gastropod-like molluscs proposed for forms which they concluded had untorted bodies.

Bouchet & Rocroi, 2005,[4] tentativley included the Macluritidae within the Gastropoda, placing them among Paleozoic molluscs with anisostrophically coiled shells of uncertain position (Gastropoda?) and within the superfamily Macluritoidea. This family has no subfamilies.

gollark: You can also fire a 100g bullet at 1000ms^-1 for 12kcal.
gollark: This isn't much of a constraint.
gollark: If you instead lift a 50kg thing 100 metres, which is useful for combat and many practical situations I'm sure, that is 12kcal i.e. about a tenth of a cereal bar.
gollark: According to `units`, the amount of energy needed to list a 100kg thing two metres is 0.4 dietary calories. That's totally manageable.
gollark: The Consortium.
