It looks like flint or chert to me rather than mudstone. Was it from a chalk area?

"No Gus. More like limestone,sandstone, and conglomerate area."- Actually , as Gus said, the rock on this website:

shows a Chert.

Flint is gray to black and nearly opaque because of included carbonaceous matter. Opaque, dull, whitish to pale-brown or gray specimens are simply called chert.
