PLATE VI. 



Asterophyllites. Sp. 



The terminal extremity of a leaf -bearing Asterophyllitic 

 branchlet. In its fragmentary state it would be useless 

 to attempt to refer it with certainty to any particular 

 species. Although apparently allied to Asterophyllites 

 longifolia, yet it seems to be distinct from it, as its leaves 

 are shorter and more numerous. 



The manner in which the terminal whorls are turned 

 upwards and squeezed together in this specimen is one 

 common in the remains of this group of plants. 



Referring to this fossil, Hutton remarks, in sending it 

 to Dr. Lindley : " Rather an unsatisfactory specimen. 

 . . . I already possess fragments from which, when 

 we get properly to understand it, I have no doubt you 

 will be able to make out several species of this interesting 

 genus." (Hutton MSS.) 



The horizon is the shale above the Bensham coal-seam, 

 and the locality, Jarrow Colliery.
