They were found in what is now Europe and North Africa.

Here is a picture of a partial Bothriolepis maxima fossil. It is missing its tail section. It was found in the "Old Red Sandstone" of the Baltic region of Europe. The fossil is now part of the Cincinnati Museum Center collection, accession number VP9132.

The creature is a placoderm of the Upper Devonian Period (375 million years ago). It is classified as a river or lake bottom dwelling antiarch.

When this picture was taken it was on display at Cincinnati Museum of Natural History and Science as of August 2013. It was donated by Walter L. Gross III.
