LOWER LIAS: RUGBY. 165 
At Hill Moreton there are brickyards showing about 20 feet 
of bluish-grey clay with small limestone-nodules, and with gravel 
and cand on top. From this locality I obtained the following 
fossils, which were named by Messrs. Sharman and Newton : 
Belemmtes. 
Ammonites brevispina. 
guibalianus. 
semicostatus. 
subplanicosta. 
Turritella Dunkeri. 
Area Strickland!. 
Gryphasa arcuata. 
cymbium. 
Unicardium cardioides. 
Bones of Ichthyosaurus, Ammonites armatus, A. Birchii, A. 
oxynotus, and Hippopodium ponderosum, have been recorded from 
this locality; while a bed with Montlivaltia rugosa, has also been 
observed, both here and at Catthorpe.* The fossils here indicate 
beds from the zones of A. obtusus to A. Jamesoni ; and the beds 
may be compared with those opened up in the Cheltenham Gas- 
works (p. 143), Mnrle Hill at Cheltenham, Drake's Broughtori, and 
Honeybourne. The occurrence of A. semicostatus is noteworthy, 
but that species is recorded by Dtimortier from the zone of A. 
A deep well made to the south east of Rugby, proved the 
following beds of Lower Lias : J

Judging from this record beds 1, 2, and 3 include the beds exposed near 
Church Lawford representing the zone of Ammonites planorbis, with a thick- 
ness 107 feet 3 inches. Beds 4, 5, and 6 include the stone worked in the Lime- 
quarries, representing the zones of A.angulatus and^4. Bucklandi, with a thick- 
ness of 157 feet 9 inches. Beds 7, 8, 9, and 10 may be taken to include the 
clays of New Bilton, and to represent the zone of A. semicostatus; while Bed 11 
no doubt includes the clays of Hill Moreton, which represent the zones of 
A. obtusus, A. oxynotus, and A. raricostatus. 
The well was carried to a depth of 1,145 feet into the Keuper " Water- 
stones," but was unsuccessful, as the water proved to be saline.
