===Neocomian===

Shallow-water platform carbonates, with some evaporites, continued to accumulate in the north (coastal area, [[Yaguajay belt|Yaguajay* belt]]). Elsewhere in central and western Cuba ([[Las Villas belt|Las Villas*]], southern [[Rosario belt]]s), the water was markedly deeper as indicated by the deposition of the [[Capitolio Formation|Capitolio*]] and [[Artemisa Formation]]s containing abundant [[nannoplankton]] (commonly rock forming) and other pelagic forms.

Some tectonic activity extended into the [[Neocomian]] (132 Ma; see Figure 27), possibly associated with the rifting, and uplifted blocks south of the Yaguajay* belt. The result was denudation of previously deposited sediments as indicated by northward shedding of carbonate clastics ([[Sabanilla Fromation|Sabanilla* Formation]]), a southward increase in basement exposures (La Rana, Tres Guanos, Rancho Veloz), and deposition of the [[Jobosi]]* arkosic conglomerate. This basement could have been derived from a continental block, here named the La Rana block (after the best exposures) and similar to the Maya or Chortis blocks, that was overridden by later nappes.
