| Cornbrash, so called from its 'brashy' or rubbly nature, an earthy oolite yielding fair land for corn. |
| Although usually conformable to the oolite, it is sometimes, as in the Jura, unconformable. |
| Lincoln itself stands on Lias beds, with a capping of the lower oolite limestone. |
| The oolite limestone beds consist of white soft limestones, having at intervals bands of marly clay. |
| These were shown to be as old at least as the oolite and lias. |
| The examples of mammalia, above alluded to, are confined to the Trias and the oolite. |
