In the Northern hemisphere the rotation of the Earth determines a counter-clockwise spin on matter. Weather, ocean currents all are related in that spin. I wonder if my snail fossils preserve the original 'spin' of the earth's rotation and have a reserved momentum. Would that be useful in analyzing gravity/spin at that time period?
If you're talking about the chirality of the shell, it has been shown that it was the expression of the dpp gene (Shimizu et al. 2013).
More trivially, if chirality had anything to do with the Coriolis effect, all gastropods from the Southern Hemisphere would be sinistral and all the ones from the Northern hemisphere would be dextral. Which is not the case.
