Fusulinacea

The Fusulinacea is a superfamily in the Fusulinida in which the test is spherical, discoida, or fusiform; commonly coiled, less often uncoiling in the late stage, numerous chambers per whorl; test wall of microgranular calcite (as for the order) in one to four layers. Tunnels or secondary foramina may result from partial resorption and secondary deposition may produce chomata, parachomate, tectoria, and axial fillings. Range: M Devonian (Givetian) - U Permian (Djulfian )

Families

The Fusulinacea, as revised in Loeblich and Tappan, 1988, includes 7 families, 27 subfamilies, and 164 genera. The families are:

gollark: The cable allows 100MHz without beeing things, but it is itself *just a cable*.
gollark: Cat5 is the cabling, bee cuboid.
gollark: Why is it impossible?
gollark: Before I got the current osmarks.net server I actually used 4000 Arduinos duct-taped together.
gollark: Just break out your laptop and open up all the panels, and keep it going up and down so nobody can stop you.
