Dr. A. Smith Woodioard — Keuper Footprint. 215 



A large slab of stone, about 8 feet by 3 feet, placed beside a stile 

 leading into the old disused quarry, had on it a number of small 

 footprints. The two sections, Cbillington and Chatwell, are about 

 seven miles apart,

Staffordshire. 



By A. Smith Woodward, LL.D., F.R.S., F.G.S. 



THE footprints from the fissile Keuper sandstones of Cbillington 

 comprise, in addition to the ordinary Cheirotherian impressions, 

 two interesting series. A number of fragments of rock covered 

 with worm tracks and castings, show several imperfectly preserved 

 footprints of a small five-toed animal, with posterior limbs of much 

 greater size than tbe anterior; and three portions of comparatively 

 smooth slabs afford evidence of a larger animal, probably of the 

 same genus, of which tbe impressions of the feet are preserved with 

 remarkable distinctness. There are also singular reticulated markings 

 upon the surface of another small slab from tbe same beds, which 

 may be interpreted as the impression of I'eptilian ( ? or labyrintho- 

 dont) skin. (See Fig. 2, p. 217.)

Of the specimens, the most noteworthy are the series of large 

 five-toed footprints, and these admit of tolerably complete description. 

 Like all the others, they are presented in the form of relief-counterparts 

 of the original impressions. The largest slab (No. I), measuring 

 0-18 m. by 0-09 m., shows two prints both of the hind- and fore-foot 

 (left side), following in natural succession ; a smaller slab (No. II) 

 exhibits one impression of each foot, partly obscured by a film
