Abstract: PREMISE The Lower Cretaceous Crato Konservat-Lagerstätte (CKL) preserves a rich flora including early angiosperms from northern Gondwana. From this area, the recently described fossil genus Santaniella was interpreted as a ranunculid (presumably Ranunculaceae). However, based… read more here.

DOI: 10.1007/s10347-018-0547-y
Abstract: The mid-Pennsylvanian (Desmoinesian–Virgilian) deposits from the Buckhorn Asphalt Quarry Lagerstätte near Sulphur, Oklahoma, are characterized by siliciclastic–carbonate rocks. One of these deposits is the ‘cephalopod coquina’ that contains a large amount of orthocerid and coiled… read more here.
