SILURIAN FOSSILS FROM LOCALITIES IN TORTWORTH.

(h) The Daniels Wood area. 
Several exposures of fossiliferous limestone occur in tlie neighbour- 
hood of Daniel’s Wood and Little Daniel’s Wood. The most southerly 
is by the stream a quarter-o£-a-mile due north of Brook Farm, where 
two distinct lithological types occur, a flaggy micaceous sandstone and 
underlying it a peculiar highly fossiliferous coarsely crystalline, some- 
times sandy, limestone with many little mud pans, occasional grit 
pebbles, abundant fragments of horny brachiopods and a considerable 
number of other fossils. The most interesting fact about this deposit 
however is that it undoubtedly contains ashy particles, and therefore 
implies either that volcanic action extended into Wenlock time, or more 
probably that we have here a small patch of Llandovery appearing in 
an area which is predominantly Wenlock. We obtained here the 
following fossils : — 
M onticuliporoid 
Favosites yothlandica ? 
Orbiculoidea riigata 
Lingula sp, 
Chonetes striatella 
Orthis elegantula 
Rhynchonella nucula 
Several small indeterminate gastropods wei-e also found. 
At about the middle of the western margin of Little Daniel’s Wood 
there are poor exposures of sandy crinoidal limestone dipping at 25 ° in 
a south-easterly direction. We obtained at this point : — 
Ctenodonta anglica I 
Orthonota sp. ? 
Bellerophon sp. 
Orthoceras sp. 
Beyrichia hlmdeni 
Primitia sp. 
Hallia sp. 
Cyathophyllum sp. 
Monotrypa cremilata 
Crinoid stems 
Spirifer elevatus 
Orthis elegantula ? 
,, rustica ? 
Orthothetes pecten 
Atrypa reticularis 
Stropheodonta jilosa ? 
P lectamhonites transver sails 
Meristina sp. 
Orhiculoidea sp. 
Beyrichia sp. 
Cornulites so. 
And in crinoidal limestone, which is poorly exposed at the southern 
end of the wood — Spirifer crispus, Whitfieldella didyma, Strophomena 
compr essay Alveolites repens; also Platyceras sp., Pterinea retroflexa^ 
Rhynchonella nucula^ Rhynchonella sp., Orthis elegantula, Chonetes 
striatella var., Orhiculoidea sp., and crinoid stems in calcareous sand- 
stone. 
(c) Tlw Charfield Green area. 
Wenlock beds are exposed in several small quarries near Oldbrook 
and Poolfield Farms, but yield few fossils in situ. The following were, 
however, obtained from blocks used in building an old wall at Pool 
Farm, these having been probably derived from one of the quarries : — 
Strophomena compressa 
Rhynchonella nucula I 
Orthis elegantula I 
Atrypa reticularis 
Pterinea retroflexa 
Cornulites sp. 
Phacops sp. 
Illcenus sp. 
Homalonotus sp. 
Beyrichia sp. 
Primitia sp. 
Crinoid stems
