The London Clay Formation is a marine geological formation of Ypresian (early Eocene Epoch, c. 54-50 million years ago) [1] age which crops out in the southeast of England. The London Clay is well known for its fossil content. The fossils from the lower Eocene rocks indicate a moderately warm climate, the tropical or subtropical flora.
Fossil seed capsules of the genus Euphorbia, found in London Clay. A list of prehistoric and extant species whose fossils have been found in the London Clay, which underlies large areas of southeast England. Plant fossils, especially seeds and fruits, are found in abundance and have been collected from the London Clay for almost 300 years. [1]
The Lambeth Group is a stratigraphic group, a set of geological rock strata in the London and Hampshire basins of southern England.It comprises a complex of vertically and laterally varying gravels, sands, silts and clays deposited between 56-55 million years before present during the Ypresian age (lower Eocene).
The London Clay is a bluish-grey marine clay with isolated pockets of fossils especially where chalkier. The youngest part of the London Clay is known as the Claygate Beds and occurs widely in Surrey. This even sandier material represents a transition between the deeper water London Clay and the succeeding shallower water, possibly estuarine ...
Scientists have found the U.K.’s largest dinosaur footprint site ever. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...
It also has many London clay fossils from the Eocene rainforest, including mammals such as Hyracotherium, the earliest ancestor of the horse. The site is important in the history of geology as fossils have been collected there for over 300 years. [4] The site is a stretch of beach which is under water at high tide.
Most significant is the stiff, grey-blue London Clay, a marine deposit which is well known for the fossils it contains and can be over 150 metres thick beneath the city. This supports most of the deep foundations and tunnels that exist under London.
There is also a range of fossils of sharks, rays and bony fish, reptiles and birds. Some of the bones occur in nodules in the clay, and much material has been washed out onto the beach. Turtles, crocodiles and snakes are represented among the reptiles, and the birds include members of sixteen families. Sheppey cliffs are also a rich ...
