The Guinea Corn Formation is a geologic formation in Jamaica. It preserves fossils dating back to the Cretaceous period.
In respect of it being the 'most diverse and thickest limestone succession with abundant rudist bivalves within the Caribbean faunal province', the International Union of Geological Sciences (IUGS) included the 'Late Cretaceous rudist bivalves of the Caribbean Province' (Rio Minho, Clarendon parish) in its assemblage of 100 'geological heritage sites' around the world in a listing published in October 2022. The organisation defines an IUGS Geological Heritage Site as 'a key place with geological elements and/or processes of international scientific relevance, used as a reference, and/or with a substantial contribution to the development of geological sciences through history.'

Dinosaur Provincial Park is a UNESCO World Heritage Site situated a two hour drive east of Calgary, Alberta, Canada; or 48 kilometres (30 mi), about a half-hour drive northeast of Brooks.
Rudists are a group of extinct box-, tube- or ring-shaped marine heterodont bivalves belonging to the order Hippuritida that arose during the Late Jurassic and became so diverse during the Cretaceous that they were major reef-building organisms in the Tethys Ocean, until their complete extinction at the close of the Cretaceous.
The Rio Minho is the longest river in Jamaica at 92.8 kilometres (57.7 mi). It rises close to the island's geographic centre, flows generally south-southwest and reaches the Caribbean Sea at Carlisle Bay in the central south coast, to the west of the island's southernmost point, Portland Point.
Caprina is a genus of rudists, a group of marine heterodont bivalves belonging to the family Caprinidae.

La Désirade National Nature Reserve is a reserve in Désirade Island in Guadeloupe. Established under the Ministerial Decree No. 2011-853 of 19 July 2011 for its special geological features it has an area of 62 ha. The reserve represents the geological heritage of the Caribbean tectonic plate, with a wide spectrum of rock formations, the outcrops of volcanic activity being remnants of the sea level oscillations. It is one of thirty three geosites of Guadeloupe.
The Basque Coast Geopark, formally the Basque Coast UNESCO Global Geopark, is an area of the Basque Country in the north of Spain which became a member of the European Geoparks Network in 2010, one of several Global Geoparks in Spain. It comprises 89 square kilometres of countryside with a 23 km long cliffed coast fronting the Bay of Biscay. Inland it comprises hilly country which reaches up to Sesiarte which is 755m above sea level. The main communities within the Geopark are Zumaia, Deba and Mutriku. The A8 Cantabrian motorway runs east–west through the Geopark.
Titanosarcolites is a genus of giant rudist bivalve from the Cretaceous. Its fossils have been found in Jamaica, Southeastern Mexico and the Southern US. It belonged to the now extinct family known as Caprinidae, a group that went extinct during the KT extinction event, 66 MYA. Titanosarcolites was one of the last members of this group. There were several species, including T. alatus, T. giganteus, T. macgillavryi and T. oddsensis.
