MmeorrPRINTS ON THE SANDS OF TIME 41 
short outer toe of the hind foot projecting at right angles to the 
line of the middle toe, but yet are not identical with those of 
any known batrachian or reptile. Still it has been conjectured 
by the same great authority, as well as by others, that these 
footprints were the work of the creatures now known as Labyrin- 
thodonts, which have left their remains in rocks of the Car- 
boniferous, Triassic, and Permian ages. Later researches have 
shown that Owen was wrong. We need not be surprised at this, 
for Paleontology has, like all the other sciences, made great 
advances the last fifty years. The researches of Marsh, Cope, 
Huxley, Fritsch, Seeley, and others, have brought to light many 
new forms of old reptiles, some of which will be described in 
later chapters. The supposed Cheirotherium probably was one 
of the Dinosaurian reptiles, and in that case these footprints were 
made by Dinosaurs. 
Our friend, Professor W. J. Sollas, has described some interest- 
ing footprints from South Wales, which probably were made by 
a Dinosaur of the Triassic age! <A friend of his was, in 1878, 
passing through the village of Newton Nottage, in Glamorgan- 
shire, when his attention was arrested by some three-toed foot- 
prints on a slab of rock, deeply impressed and rendered par- 
ticularly visible by the slanting rays of the setting sun. Casts of 
them were afterwards made by the curator of the Cardiff Museum 
(Mr. J. Storrie). 
To show how valuable geological finds are often neglected 
through ignorance of their real worth, it may be mentioned here 
that this slab even in 1894 was lying in a corner of the village 
green, in front of the church; formerly it lay in front of the steps 
of the inn, where it consequently suffered more or less wear. The 
impressions remind one of some of those described by Professor
