132 LIAS OF ENGLAND AND WALES : 
It was from this neighbourhood that a specimen of the Spiri- 
ferina was first figured by John Walcott* Moore notes the 
occurrence of Ammonites Bucklandi, A. Conybearei, A. angulatus, 
A. Turneri, &c. The old pit is situated about \ mile N.N.E. of 
the church, and having long been disused when I visited it in 
1885, in company with Mr. Martin F. Woodward, we had great 
difficulty in finding the Spirifer bank. In the lowest beds of hard 
grey shelly limestone, Belemnites and Rhynchonella variabilis were 
met with ; and above, there were 5 or 6 feet of clay and sandy 
shales (with lumps of Carboniferous Limestone and occasional 
quartz pebbles), in the lower part of which S. Walcotti and Gryphcca 
arcuata were found. Pkoladomya ambigua and Ammonites bisulcatus 
also occurred. 
A somewhat similar section to that at Camerton, was exposed 
at Medyeat near Timsbury ; there the Foraminifera zone (stiff 
blue clay, 7 ft. 6 in. thick), was exposed above the Spirifer-bed, the 
former being grouped by Prof. Tate in the zone of A. oxynotus. 
This classification must be regarded as approximate, for at 
Camerton Moore found A. semicostatus in the bed above the 
Foraminifera Zone.f (See p. 131.) 
The following section in a quarry below Timsbury was noted 
by TawneyJ :

Tawney observed that he had not obtained Ammonites angulatus anywhere 
in the district. Prof. Tate. however, grouped the lower beds of Lias at 
Medyeat with that zone, and Moore has recorded the species from Camerton.
