Could it be an overly pyritized ammonite? The links below indicate the area is known for it.
"bubbly" appearance is due the growth of the pyrite by bacteria when the ammonite was buried in the seabed about 1 metre, 195 million years ago.
This is one of the examples from above. I would recommend also posting in those forums.
