THE JURASSIC PERIOD. 



Dapedius (Fig. 152) and Aspidorhynchus (Fig. 153), while others, 

 like the superb Lepidotus, were very large, evidently the kings of 

 their time and race. Some of the Jurassic fishes approximate the 

 Teleosts so closely that it seems arbitrary to call them Ganoids. 

 Caturus, Leptolepis, Hypsocormus (Fig. 154), and Megalurus are 

 much like what the ancestral Teleosts must have been.
