It is almost wholly basaltic, but has some oolite at the head of the bay on its north side.
The name of Archaeopteryx litho graphica was based by Hermann von Meyer upon a feather (Gr.irrEpv, wing) found in 1861 in the lithographic slate quarries of Solenhofen in Bavaria, the geological horizon being that of the Kimmeridge clay of the Upper Oolite or Jurassic system.
The earliest forms, from the Lower Oolite and later, belonging chiefly to the extinct family Prosoponidae, have been shown to have close relations with the most generalized of existing Brachyura, the deep-sea Homolodromiidae, and to link the Brachyura to the Homarine (lobster-like) Macrura.
The fossils are all characteristic Oolite forms and include species of Hemicidaris, Pholadomya, Ceromya, Trigonia and Alaria.
Their relation to the Antalo limestones is uncertain, but Blanford considers them to be not later in age than the Oolite.
The Great Ouse, from the point where it enters the county on the west, has carved through the Middle Oolites and exposed the Great Oolite as far as Bedford; their alternating limestones and clays may be seen in the quarries not far from the town.
Westward of and above these strata, the Middle and Upper Jurassic formations are found (Lias, Lower Oolite, Oxfordian, &c.), with well-marked and numerous fossils (Ammonites, Nerinaea, Natica, Astarte, Rhynchonella, Echinodermata, &c.); then the Cretaceous rocks, both these and the Jurassic series being largely developed, the Cretaceous fossils including Nautilus, Belemnites, Ostrea, Gryphaea, &c., and some very large Ammonites (Pachydiscus).
In the beds of the Lower Oolite portions of the skull of a reptile resembling the gavial of the Ganges had been previously discovered, from which a new genus called Steneosaurus has been founded.
To this succeed the Oolite formations.
The Inferior Oolite, somewhat narrower than the Lias, extends from the boundary with Rutland due north past Lincoln to the vicinity of the Humber; it forms the Cliff of Lincolnshire with a strong escarpment facing westward.
The principal member of the Inferior Oolite is the Lincolnshire limestone, which is an important water-bearing bed and is quarried at Lincoln, Ponton, Ancaster, and Kirton Lindsey for building stone.
Eastward of the Inferior Oolite lie the narrow outcrops of the Great Oolite and Cornbrash.
The Middle Oolite, Oxford clay and Corallian is very narrow in the south near Wilsthorpe, widening gradually about Sleaford.
The Upper Oolite, Kimeridge clay, starts from the vicinity of Stamford, and after attaining its greatest width near Horncastle, runs north-north-west to the Humber.
In the Cretaceous system of the Wolds, the Lower Greensand runs nearly parallel with the Upper Oolite past South Willingham to the Humber.
The rest of the county, comprising all its south-east portions between the Middle Oolite belt and the sea, all its northeast portions between the chalk belt and the sea, and a narrow tract up the course of the Ancholme river, consists of alluvial deposits or of reclaimed marsh.
Freestone is quarried around Ancaster, and good oolite building stone is quarried near Lincoln and other places.

It has been suggested that one at least of the flowers, that originally described by Mr Carruthers from the Inferior Oolite of Yorkshire as Beania gracilis, may have been borne by a member of the Ginkgoales.
be best compared with such leaves as those of the G, Baiera leaf, Inferior Oolite, England.
Seeds like those of Ginkgo biloba have also been recorded as fossils in Jurassic rocks, and it is possible that the type of flower known as Beania, from the Inferior Oolite rocks of Yorkshire, may have been borne by Ginkgo or Baiera.

He appears to have been the first to introduce the term oolithus to rocks that resemble in structure the roe of a fish; whence the terms oolite and oolitic. He died at Wolfenbiittel on the 21st of March 1753.
There is good evidence for supporting Professor Williamson's conclusions as to the organic connexion between the flowers, originally described from Inferior Oolite rocks of Yorkshire and subsequently named Williamsonia (fig.
Dorsetshire and in the Inferior Oolite beds of Yorkshire, as well as in Rhaetic strata in Persia and elsewhere; it is characterized by its bipinnate fronds, and may be compared with the recent Australian genus Bowenia - peculiar among living Cycads in having bipinnate fronds.
