| The examples of mammalia, above alluded to, are confined to the Trias and the oolite. |
| In the process of being buried under other sediments, these ooids can fuse into a solid mass of sedimentary rock called oolite. |
| Lincoln itself stands on Lias beds, with a capping of the lower oolite limestone. |
| At Taskent the upper layer of oolite is more resistant but sharply truncated beneath stromatolites of the overlying Gevne Formation. |
| Although usually conformable to the oolite, it is sometimes, as in the Jura, unconformable. |
| The oolite limestone beds consist of white soft limestones, having at intervals bands of marly clay. |
