Outcrops of the Late Cretaceous (Campanian) aged Aguja Formation, Big Bend National Park, Texas, USA
Osgodby Formation (Middle Jurassic) exposed on the shore of Cayton Bay, North Yorkshire.
Matmor Formation (Jurassic, Callovian) exposed in Makhtesh Gadol, Israel. (Electricity pylon for scale).
An atypical (without intertidal and supratidal environment) carbonate platform settles down along the margin. Shallow water oolithes and oncoids are deposited in a narrow zone between a basin with Cancellophycus to the north and a marine/swampy plain with abundants mollusc fauna. However the Mytilus formation, rich in bathonian and callovian foraminifera (Septfontaine, 1984 etc.), develop thick limestone beds tenth of meter above, wrongly attributed to the upper Jurassic. See discussion in Septfontaine (1984).

Size of Austroraptor cabazai compared to a human, a species of Dromaeosaurid Unenlagiinae who lived during the Cretaceous period in Argentina, more precisely in the Allen Formation.

Laplatasaurus araukanicus has been restricted to its lectotype which hails from the Anacleto Formation.[17]
Abelisaurus comahuensis could either belong to the Allen or Anacleto formations.[12]
Pellegrinisaurus powelli could either belong to the Allen or Anacleto formations.[18][19]
