Safe to say that it is probably an aquatic arthropod, and possibly one with an oval body plan (judging by the 'resting place'). Do we know the age of it?

Diplichnites isp. - trackways, preserved in hypo-and epirelief, 1-2 cm wide, consisting of two parallel rows of straight or slightly curved, smooth oval ridges or slightly elongated tracks, 0'5-2 mm wide, orientated transverse or oblique to the mid-line, distributed in an opposite or staggered arrangement.

Judging by the table of contents, the whole of this book looks fantastic (and I spotted Fortey in there as a contributing co-author on one of the articles :megdance:).

It is highly unlikely that there is anything there to prep out. The feature we see is a cast, infilled by sediment.
Still, much can be deduced about the creature by studying the marks it left when making its resting place.

The wide track and oval resting trace were probably produced by a large cheloniellid arthropod.

I have to admit a slight bias.  Here is a large 15 cm cheloniellid from my collection:

Duslia insignis - Upper Ordovician, Lower Ktaoua Formation, Kaïd Rami, Morocco
