Summary

Description
English: Original image caption: Cliff exposures at Lavernock Point, National Grid reference ST 187681.
(A) The base of the Jurassic showing a series of alternating limestones and mudstones. The new specimen is most likely from the higher of two limestones indicated in yellow that contain a thin shelly horizon, but it was recovered from the fallen blocks in front of the exposure. The upper of the two matches most closely the bed thickness of the slabs with the dinosaur bones. (B) The same beds in stratigraphic context with the highest occurrence of conodonts, the lithological base of the Jurassic and the first occurrence of the ammonite Psiloceras planorbis indicated.
Deutsch: Steilküstenaufschluss bei Lavernock Point, National-Grid-Koordinaten ST 187681.
(A) Die basalen Schichten des Jura bestehen aus einer Wechsellagerung von Kalksteinen und (Silt-)Tonsteinen. Das neue Exemplar stammt höchstwahrscheinlich aus der oberen, eine dünne Schillage enthaltenden Bank der beiden gelb markierten Kalksteinbänke, gefunden wurde es jedoch im Blockschutt vor dem Kliff. Die obere der beiden passt von ihrer Mächtigkeit am ehesten zu den Platten mit den Dinosaurierknochen. (B) Die gleichen Schichten im stratigraphischen Zusammenhang mit Kennzeichnung des letzten Auftretens von Conodonten, der lithologischen Basis des Jura und des Erstauftretens des Ammoniten Psiloceras planorbis.
