Looks like it has dropped out of the glacial till.  The linear scratches would have been made during transportation in the ice, grinding against other fragments or country rock.  The lithology?  Rather difficult to tell from a photo.  If it fizzes with dilute acid and can be scratched with a knife, it's a limestone.  But my first impression is that it might be an extremely fine-grained basalt, in which case it is a volcanic lava, will neither react with acid nor scratch with a hard metal knife.  It could have come from anywhere in a broad arc from the northwest to the east (Scotland to Scandinavia).  One last possibility you can check...if it feels light, can be carved and leaves a brown streak when rubbed against unglazed china, then it is probably jet.

Could it be a waterworn piece of jet? There's plenty in the area
