Salt glands in a Tithonian metriorhynchid crocodyliform and their physiological significance

Lethaia, 2000
Our knowledge of Mesozoic tetrapods is based mainly on osteological evidence. The discussion of the evolution of any homeostatic system is highly speculative because direct non-osteological evidence is uncommon. Here we report an extraordinarily well-preserved cast of a pair of lobulated protuberances in the skull of the marine metriorhynchid ...

The bivalve Aulacomyella from the Early Tithonian (Late Jurassic) of Antarctica

Antarctic Science, 1991
The bivalve Aulacomyella is described formally from Tithonian deposits of the Antarctic Peninsula region for the first time. Two species are recognized. A. willeyi Kelly sp. nov. was collected in situ from the Nordenskjöld Formation, Longing Gap on the east coast of Graham Land, and in clasts reworked into Cretaceous glide block deposits on James Ross ...

Fishes from the Akkuyu Formation (Tithonian),Western Taurus, Turkey

Geobios, 1985
Abstract Two fragmentary fishes are described from theUpper Jurassic (Tithonian) Akkuyu Formation of the Akseki region in the western Taurus (Turkey). Both are determinable, one as a caudal fin of an ichthyodectiform teleost, either Thrissops or Allothrissops , the other as a coelacanthid coelacanth, cf. Undina .

Caribbean Lower Tithonian ammonites from central-east Mexico

Geobios, 2009
Imlay's ammonite species Paradontoceras butti and Paradontoceras antilleanum are first reported from central-east Mexico under precise stratigraphic control. Mexican and Cuban ammonites referred to these species have been studied and proved to have been gathered from a relatively limited area within the southern paleomargin of the north American Plate,

Earliest known Porcellanidae (Decapoda: Anomura: Galatheoidea) (Jurassic: Tithonian)

Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, 2010
Jurellana tithonia n. sp. is the earliest known Porcellanidae, from the Tithonian Ernstbrunn Limestone, Austria. Porcellanids are well-known from the fossil record, already having been described from Cretaceous, Eocene, and Neogene rocks. Their occurrence in the Jurassic is not surprising, because the Infraorder Anomura, to which they belong, is the ...

Upper Tithonian limestone with Campbelliella striata (CAROZZI)

2007
In the continuous sequence of Upper Jurassic strata during the late Tithonian, in the well bedded limestone with shallowing upward cycles, the dasyclad species Campbelliella striata (CAROZZI) was common, in addition to Clypeina jurassica FAVRE (= Clypeina sulcata (ALTH)) and Salpingoporella annulata CAROZZI. Generally, C.

Ophiolitic melange and flyschoidal sediments of the Tithonian–Lower Cretaceous in Albania

Terra Nova, 1990
ABSTRACTOphiolitic melange and flyschoidal sediments of the Tithonian‐Lower Cretaceous age are widespread in the Eastern Albanides. They lie transgressively or normally on top of the ophiolitic sequence through radiolarian cherts of the Kimmeridgian‐Tithonian age, or on top of the carbonate sequence of the periphery of the ophiolites through Middle ...
