From Wiki: The word “gastropod” is derived from the Ancient Greek words γαστήρ (gastér, stem: gastr-) “stomach”, and πούς (poús, stem: pod-) “foot”, hence stomach-foot. Wikipedia has an excellent article on gastropods HERE.

Nice concise list of what has been found here. Lists some of the name changes since 1892.
Paper about gastropods

300+ page downloadable pdf written in 1892. The “Lower Silurian” was part of the Ordovican until the mid 1900’s.
My experience in Fillmore County is that the most common gastropod to be found is the
Maclurites species
Only about 1 in 50 Maclurites are Maclurites crassus that I find.
I have a very good post with excellent pictures on Maclurites HERE:

Second most common gastropod that I find is the
Hormatoma species
Probably the third most common is the
Liospira species
These remind me of “skipping stones” because of their distinct flatness.
Fusispera species
Holopea species
Trochonema species
Subulites species
