The Serpukhovian Book Canyon Conglomerate is an unpublished limestone conglomerate contained within the Tyler Formation in central Montana. It overlies and contains clasts of the Bear Gulch Limestone, a plattenkalk deposit yielding amazing paleontological detail. The Book Canyon Conglomerate is up to 2 m thick, markedly lensoid, and laterally discontinuous in its outcrop for a distance of 2 km but likely extends beyond the study area. Well logs and cores indicate its presence in the subsurface…

Diagenesis of plattenkalk: examples from the Solnhofen area (Upper Jurassic, southern Germany)

The Upper Jurassic (Tithonian) plattenkalk successions in the Solnhofen/Eichstätt area consist of alternations of thin‐bedded, laminated, fine‐grained, very pure limestones (so‐called ‘flinz beds’)
