Boa Blanchardensis
''Boa blanchardensis'', also known as the Marie-Galante boa, is an extinct species of ''Boa'' from the island of Marie Galante in the Lesser Antilles. It lived on the island during the Late Pleistocene until approximately 15.000 years ago when it went extinct for unknown reasons. With an estimated length of up to , it was the largest terrestrial vertebrate on the island. Discoveries of fossil bones in caves suggest that it may have at least occasionally hunted bats. Discovery and naming The fossils of ''Boa blanchardensis'' are exclusively known from three caves on Marie-Galante in the Guadeloupe archipelago. These three caves consist of the Cadet 2 cave, Cadet 3 rock shelter and Blanchard Cave, the later providing the vast majority of fossil material. Within these caves the ''Boa'' fossils were exclusively found in the older Pleistocene sediments and absent in those dating to the Holocene. The Marie-Galante snake fossils were identified and catalogued in various studies before bei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period (Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological ...

Histology
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Although one may divide microscopic anatomy into ''organology'', the study of organs, ''histology'', the study of tissues, and ''cytology'', the study of cells, modern usage places all of these topics under the field of histology. In medicine, histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. In the field of paleontology, the term paleohistology refers to the histology of fossil organisms. Biological tissues Animal tissue classification There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these four principal tissue types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saladoid
The Saladoid culture is a pre-Columbian indigenous culture of territory in present-day Venezuela and the Caribbean that flourished from 500 BCE to 545 CE. The Saladoid were an Arawak people. Concentrated along the lowlands of the Orinoco River, the people migrated by sea to the Lesser Antilles, and then to Puerto Rico."Prehistory of the Caribbean Culture Area" Southeast Archaeological Center, National Park Service (retrieved 19 July 2013) Name This cultural classification comes from adding the suffix "oid" to the sites where these unique pottery styles were first recognised; thus the name Saladoid, from name of the modern settlement of Saladero, is used by archaeologists to identify the peoples of the early ceramic age.Chronology The Saladoid period includes ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colubridae
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Grande-Terre
Grande-Terre Island (french: île de Grande-Terre / île de la Grande-Terre; gcf, label=Antillean Creole, Gwantè) is the name of the eastern-half of Guadeloupe proper, in the Lesser Antilles.

To the east lies La Désirade, to the south lies Marie Galante Despite its name, Grande-Terre (literally "Large Land" in French) is smaller than Basse-Terre Island. It was called like that, in contrast with the much smaller Petite Terre Islands ("Small Land" Islands), two very small islands located about 10 km south-east of the Grande-Terre (see map to the left). Grande-Terre's indented coastline is surrounded by coral reefs and the island itself is a limestone plateau. Its surface is a series of rolling hills, white sand beaches and cliffs. The ...

La Désirade
La Désirade is an island in the French West Indies, in the Lesser Antilles of the Caribbean. It forms part of Guadeloupe, an overseas region of France.

Spanish colonization Deseada was the first island sighted by Christopher Columbus in 1493. When he landed there during his second voyage to America, he took possession of the island on behalf of the Spanish crown, followed by the island of Marie-Galante. Like other Antillean islands, it served as a hideout for pirates or corsairs who attacked Spanish overseas possessions. Some sources indicate that the island owes its name to the relief of the members of Columbus crew who saw the first dry land since leaving the Canary Islands of Spain. They cried out: "Oh, desired island" The French name ''La Désirade'' is an adaptation of its historical name in Spanish (''La Deseada'') ...

Saint Vincent (Antilles)
Saint Vincent is a volcanic island in the Caribbean. It is the largest island of the country Saint Vincent and the Grenadines and is located in the Caribbean Sea, between Saint Lucia and Grenada. It is composed of partially submerged volcanic mountains. Its largest volcano and the country's highest peak, La Soufrière, is active, with the latest episode of volcanic activity having begun in December 2020 and intensifying in April 2021.
