Stratigraphy
Formation:Ceru di Cueba
Stratigraphic resolution:formation
Stratigraphy comments: Collection derived from several horizons within the Ceru di Cueba Formation. Based on foraminifera the formation has been considered Late Eocene in age (Rutten (1928), Molengraaf (1929) and Rutten and Vermunt (1932), while Koch (1928, 1929) favors an Oligocene age. Rutsch favored a Late Eocene age and correlated the unit to the San Fernando beds of Vista Bella Quarry, Trinidad. Jung (1974) discounts an Oligocene age and suggests a middle or Late Eocene age. Foraminiferal evidence favors correlation to a late Middle Eocene age Santa Rita Formation of Venezuela. Jung (1974) suggests the Ceru di Cueba Formation should be correlated with the Ceru Mainsjie Formation, which would indicate a late Middle Eocene age. Assigned a Bartonian age on this basis.
Lithology and environment
Primary lithology:pebbly lithified sandy "limestone"
Secondary lithology: poorly lithified calcareous claystone
Includes fossils?Y
Includes fossils?Y
Lithology description: Succession of limestones, with intercalations of sandstones, grits and conglomeratic layers, with small well rounded pebbles.
Environment:open shallow subtidal
Geology comments: Contains normal salinity faunas, coarse limestones with abundant larger foraminifera, one partially oolitic bed, and (in the basal unit) pebbles of underlying diabase bedrock and older formations. It is possible that these are resedimented deposits in deep water, but they are described as transgressive over the underlying igneous substrate, so a shallow subtidal environment is entered.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection methods:selective quarrying,field collection
Reason for describing collection:general faunal/floral analysis
Museum repositories:NMB
Collection method comments: Collections reposted in the Naturhistorisches Museum Basel (NMB). Collected by P. Jung (1971).
Taxonomic list comments:Exhaustive for Mollusca, although the authors suggest that careful collecting would yield further taxa. Eocene fossils from region have been reported previously by Hummelinck (1940) and mentioned by Molengraaf (1929), Rutsch (1939), and Schaub (1948).
