Rhynchonelliform brachiopod Jurassic
This small (2 cm from ventral beak to anterior edge) brachiopod with a short curved hinge is strongly ribbed and has a characteristically deep fold in the dorsal valve and corresponding sulcus in the ventral valve. The zig-zag commissure enabled the brachiopod to increase the area open between the two valves, and hence increase nutrient intake, whilst restricting the entrance of larger particulate matter. The brachiopod was attached to the substrate by a small pedicle.

This is common knowledge that disaster is everywhere. Its in the streets, its inside your campuses, and it can even be found inside your home. The question is not whether we are safe because no one is really THAT secure anymore but whether we can do something to lessen the odds of ever becoming a victim.
