Lost seas, lakes, and lagoons: terminal Jurassic strata and environments in Buckinghamshire, English south midlands.

The Jurassic strata running through the county of Buckinghamshire, English south midlands, culminate in the marine to non‐marine Upper Tithonian (formerly Portlandian) Portland and Purbeck formations. Despite poor exposure, this richly fossiliferous and strongly regressive carbonate‐clastic succession allows reconstruction of shallow marine, coastal lagoonal and ultimately lacustrine environments, against the backdrop of a hot, greenhouse climate.
