Yes, a Petoskey stone is a type of sedimentary rock. It is formed from the remains of ancient coral reefs found in freshwater deposits in Michigan, USA. The stone is composed of fossilized coral, which gives it its distinct pattern.

Is a petoskey stone clastic?

A "petoskey" stone was originally an fossiliferous (with a coral fossil), organic (sedimentary) limestone. The original limestone has been glaciated and pieces of the fossiliferous limestone containing the corals have been plucked form their bedrock matrix and rounded into pebbles as they have been carried along by ice. When the ice melted these pebbles have been dropped into whatever was below them. This means a petroskey stone is a clast in a "new", modern clastic rock. However the stones themselves are not originally from a clastic rock, they are sedimentary in origin.
