Your second photo shows enough of the fossil's characteristics for me to say it is a Rugosa (Tetracorallia) fossil. I recognize it because I found very nice specimens when I was a spelunker (cave-explorer) 50 years ago. Some of my finds were broken open, like yours on one side, showing the distinctive semi-parallel ridges of a Tetracorallia coral's interior.
From the Wikipedia entry:
https://en.wikipedia.org/wiki/Rugosa
The Rugosa, also called the Tetracorallia, are an extinct order of solitary and colonial corals that were abundant in Middle Ordovician to Late Permian seas.[SUP][2][/SUP]
