The Yanigua Formation is a geologic formation in Dominican Republic. The lagoonal claystones and marls preserve fossils dating back to the Miocene period. [1] The formation hosts Dominican amber.
Dominican amber is amber from the Dominican Republic derived from resin of the extinct tree Hymenaea protera.
Hybosoridae, sometimes known as the scavenger scarab beetles, is a family of scarabaeiform beetles. The 690 species in 97 genera occur widely in the tropics, but little is known of their biology.
Aureofungus is an extinct monotypic genus of gilled fungus in the order Agaricales. At present it contains the single species Aureofungus yaniguaensis.
Cephalotes alveolatus is an extinct species of ant in the subfamily Myrmicinae known from a single Middle Miocene fossil found in amber on Hispaniola. At the time of description C. alveolatus was one of seven fossil ant species placed in the Cephalotescoffeae clade.
Cephalotes caribicus is an extinct species of ant in the subfamily Myrmicinae known from two Middle Miocene fossils found in amber on Hispaniola. At the time of description C. caribicus was one of nine ant species placed in the Cephalotespinelii clade.
Cephalotes dieteri is an extinct species of ant in the subfamily Myrmicinae known from two Middle Miocene fossils found in amber on Hispaniola. At the time of description, C. dieteri was one of seven fossil ant species placed in the Cephalotescoffeae clade.
Cephalotes hispaniolicus is an extinct species of ant in the subfamily Myrmicinae known from a single Middle Miocene fossil found in amber on Hispaniola. At the time of description C. hispaniolicus was one of six ant species placed in the Cephalotesmultispinosus clade.
The Gatún Formation (Tg) is a geologic formation in the Colón and Panamá Provinces of central Panama. The formation crops out in and around the Panama Canal Zone. The coastal to marginally marine sandstone, siltstone, claystone, tuff and conglomerate formation dates to the latest Serravallian to Tortonian, from 12 to 8.5 Ma. It preserves many fossils, among others, megalodon teeth have been found in the formation.
The Lagunitas Formation is a geologic formation in Cuba. The open marine, fluvio-deltaic and lagoonal claystones, limestones and conglomerates preserve fossils dating back to the Early Miocene period. Among others, the fossil primate Paralouatta marianae, the largest primate of the Miocene New World, was found in the formation. Based on microfossils, the age has been determined as Burdigalian.
The Baitoa Formation is a geologic formation in Dominican Republic. The formation consists of siltstones and limestones deposited in a shallow marine to reef environment. The formation, unconformably overlying the Tabera Formation and unconformably overlain by the Cercado Formation, preserves bivalve, gastropod, echinoid and coral fossils dating back to the Burdigalian to Langhian period.
The Cercado Formation is a geologic group in Dominican Republic. The formation comprises siltstones, limestones, claystones, sandstones and conglomerates deposited in a shallow marine to reef environment. The Cercado Formation, unconformably overlying the Baitoa Formation, preserves bivalve, gastropod, decapod and coral fossils dating back to the Late Miocene to Early Pliocene period.
The Cerros de Sal Formation is a geologic formation in the southern Dominican Republic. The coastal claystone preserves coral fossils dating back to the Late Miocene period.
The La Toca Formation is a geologic formation in the northern and eastern part of the Dominican Republic. The formation, predominantly an alternating sequence of marls and turbiditic sandstones, breccias and conglomerates, is renowned for the preservation of insects and other arthropods in amber, known as Dominican amber. The formation is dated to the Burdigalian to Langhian stages of the Miocene period.
This list of fossil arthropods described in 2009 is a list of new taxa of trilobites, fossil insects, crustaceans, arachnids and other fossil arthropods that have been described during the year 2009, as well as other significant discoveries and events related to arthropod paleontology that occurred.
Mesembrinella caenozoica is an extinct species of blow fly in the family Mesembrinellidae. The species is solely known from the Middle Miocene Dominican amber deposits on the island of Hispaniola.
Enischnomyia is an extinct genus of bat fly in the family Streblidae. At the time of its description the new genus comprised a single species, Enischnomyia stegosoma, known from a single Miocene fossil found on Hispaniola. E. stegosoma was the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. The species is host for the plasmodiid Vetufebrus ovatus preserved in its salivary glands and midgut.
The geology of the Dominican Republic is part of the broader geology of Hispaniola with rocks formed from multiple island arcs, colliding with North America.
Merkurosaurus is an extinct genus of lizards from the Shinisauria that is known from the Late Oligocene of Germany, collected in 1999, and the Early Miocene Most Formation of the Czech Republic and the Wiesbaden Formation Germany of (Amöneburg). A single species, M. ornatus, is known and was named and described by Jozef Klembara in 2008 based on the holotype Pb 02045 and other referred specimens. It was initially only known from deposits in the Czech Republic but remains found in Germany were eventually attributed to the genus in 2015.
