part 2] INFERIOR OOLITE OF THE CREWKJERNE DISTRICT. 165 



In the old working the beds mentioned may be seen after a 

 little excavating has been done. 



The rock of garantianm hemera is very interesting, on account 

 of its highly fossiliferous nature. 



The limestone dated murchisoncB-Ancolioceras is separable into 

 three layers — the upper two (equivalent to the Blue and Red Beds 

 of Misterton), 22 inches thick; the lowest (equivalent to the 

 Grey or Cockle Bed), 10 inches thick. 



The Scissum Beds are not exposed ; but the quarryman said that 

 the quarry was not worked deeper, because only soft sandy rock 

 would be encountered. 



Haselbury Plucknett.— In times past there was a quarry of 

 considerable extent situated to the south of the church (29). It 

 is now rilled in, and serves as a small common for the village. 

 Doubtless this was the quarry visited by Hudleston, concerning 

 which he wrote l : 



' This is a place of considerable importance as a quarry, but it is more 

 remarkable for Echini and conchifera than for gasteropoda. Isocardia 

 cordatd is a noteworthy fossil here, since its occurrence in Dorset has not 

 often come under my notice.* 



' It must be allowed that Profile No. 3 [that is, of this Haselbury section] 

 is very inferior in interest ... to the two preceding [Burton-Bradstock Cliff 

 and Vitney or Vinney Cross], since but few gasteropoda are noted from this 

 quarry. I have introduced it mainly to show the preponderating importance 

 of the Lower Division, and especially of the March isonx zone in this area. 

 The massive shell-bed with keeled ammonites certainly represents nothing 

 higher than the concavns (Sowerbyi) zone, whilst all the rest must be in the 

 Murchisonx zone or lower. The gasteropoda are probably on the same 

 line as at Drympton, which I conceive to be towards the base of the 

 Murchisonx zone.' 



* Specimens of this fossil are not uncommon in the beds of (1) Murchisonx 

 and (2) Ancolioceras-scissi hemerse at the Marston-Road Quarry, near Sher- 

 borne.
