Recently, George Witaszek sent us photos of a rare Mazon Creek fossil. He found fossils of the inner bark of Asolanus camptotaenia. A. camptotaenia was described by Horatio Curtis Wood in 1860, “Contributions to the Carboniferous flora of the United States“, Acad. Nat. Sci. Philadelphia Proc. 1860 12: 236-240. The locatity and position for the material Wood used were unknown.

A. camptotaenia, n . sp.-Stem striate ; striæ disposed in two series; in the one, contiguous, numerous, descending towards the right; in the other, few, and ascending towards the right; cicatrices sub- triangular rounded at apex, acuminate at the base; vascular scars almost obsolete. Locality and position unknown. Cabinet of the Academy.

That’s a very interesting fossil, George! Thanks for sharing!
