Weston quarries and occasionally at Storeton. Professor 

 Seeley considered that it bore much resemblance to a 

 South African form (Keirognathus). The size of the foot 

 would about suit such an animal as Gordonia Traquairi. 



These footprints have always been attributed to 

 Chelonia since they were first observed, but we have no 

 record of remains of Triassic Tortoises or Turtles having 

 been found in this country, and though negative evidence 

 is of little value, I think it would be safer to assign these 

 to an Anomodont than a Chelonian. I may just note in 

 passing that the small oval mark with marks of the claws 

 figured in Morton's Greol. Liv., and called by Professor 

 Ant, Fritsch Saurichnites perlatus, and comparatively 

 common here, is remarkably like the footprint of a 

 Terrapin, but there are intermediate forms that tend to 

 connect it with the one supposed to be the footprint of an 

 Anomodont. 



Dinosattria. Though the Dinosaurs flourished in the 

 later part of the Mesozoic period, we find traces of them 

 in the Keuper in the neighbourhood of Bristol. With 

 their general form you are doubtless familiar. There is 

 a great discrepancy in the size of the fore and hind limbs. 

 This discrepancy is also said to be shared by some of the 

 earlier forms of the Crocodilia, but it is so great in some 

 Dinosaurs that there is every probability that they walked 

 on their hind legs, and as they reached, if not exceeded, 

 the size of our largest Mammals, they must have presented 

 a somewhat formidable appearance. The supposed bipedal 

 forms were probably carnivorous, the quadrupedal herbi- 

 vorous. Many most startling restorations have been made, 

 but it seems to me that any of us with the skeleton before 

 us can bring before our minds a sufficient picture of its 

 general form. 



It has been thought that we have here a forerunner
