OUR COMMON BRITISH FOSSILS. 



see them forming the hills which flank the railway 

 on the right-hand side. Numerous quarries, for road- 

 material, limestone, and ironstone, are opened in them, 

 where plenty of fossil mollusca can be collected. 

 Perhaps the best collecting-grounds for Oolitic fossils 

 in Lincolnshire are at Weldon, Wakerley, the neigh- 

 bourhood of Stamford (as at Squire's Stone quarry), 

 Wild's Ford, Kingscliffe, Stibbington, Whittering, 

 Wrawly, Brigg, Market Rasen, and Horncastle.

ever, for Oolitic fossils. The great Oolite formation 

 extends from the middle of Lincolnshire to Gloucester- 

 shire, and quarries for various purposes are opened 

 in it more or less along its entire course, where fossils 

 abound, among which bivalves and univalves are the 

 most numerous. There are also plenty of places in 

 Bedfordshire (as in Cowper's county), Rutland- 

 shire, Buckinghamshire, and Oxfordshire, as well as 

 Gloucestershire (which last county is nothing if not 

 Oolitic),, Somersetshire, Wiltshire, Dorsetshire, etc.
