La Catalina section, Sierra del Rosario, western Cuba - V (Jurassic of Cuba)
Where: Cuba (22.7° N, 83.4° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: La Zarza Member (Artemisa Formation), Tithonian (149.2 - 143.1 Ma)
• group of beds-level stratigraphic resolution
Environment/lithology: basinal (); lithified limestone and lithified, calcareous shale
• The Lower Tithonian sediments of the Sierra del Rosario were laid in somewhat deeper and calmer water, but also in a poorly ventillated basin. Turbidity currents and submarine slumps contributed to the sedimentation. The Upper Tithonian strata of the Sierra del Rosario were laid down in conditions of lower energy but even there coquinas composed of ammonite shells or aptychi were locally accumulated. The uppermost Tithonian sediments display features of deep-water sedimentation.
• 0.5 m. Light-coloured and spotted limestone. Locally the layer surfaces are uneven. There ara some intercalations of marly shale.
