Predator-trap?

[Dinosaur L <DinosaurL@aol.com>]

Recently during a class discussion of predator traps, different bonebeds were
mentioned as possible "predator trap" conglomerates.  There is an Allosaurus
bonebed in Utah of (I believe) 44 individuals - the actual site was not
remembered by our professor, nor was she able to locate info on whether there
were other species of dinosaurs in conjunction with the allosaurs.  Does
anyone know if there were any other types of dino's along side?  Any refs?

Thanks in advance,
