Quicksand Fans

Hello. I had thought about coming here for some time, and would like to know if anyone has seen anything with snakes or dinosaurs in quicksand?

I recall and old movie titled "Beast of Hollow Mountain" in which a fearsome prehistoric dino was eventually dealt with by being lured into quicksand and drowned. That's not before a couple of guys also became trapped in the same quicksand, but they survived.

Dinosaurus--An old 60's movie I used to love as a kid and only recently rediscovered. It has a pretty good stop motion sinking scene featuring a Brontasaurus. Not to mention a guy beating up a T-Rex with an old timey steam shovel.

I remember both of those ^^
