Mobulidae
The Mobulidae (manta rays and devilfishes) are a family of rays consisting mostly of large species living in the open ocean rather than on the sea bottom. Taxonomy The Mobulidae have been variously considered a subfamily of the Myliobatidae by some authors, and a distinct family by others, but recent work favors the latter. Two genera have been traditionally recognized, ''Manta'' and ''Mobula'', but recent DNA analysis shows that ''Mobula'' as traditionally recognized is paraphyletic to manta rays, making ''Manta'' a junior synonym of ''Mobula''. Fossil record Several genera of fossil mobulids are known, including ''Archaeomanta'', '' Burnhamia'', '' Eomobula'', and ''Paramobula ''Paramobula'' is an extinct genus of ray in the family Myliobatidae (eagle rays).

Manta Ray
Manta rays are large rays belonging to the genus ''Mobula'' (formerly its own genus ''Manta''). The larger species, '' M. birostris'', reaches in width, while the smaller, '' M. alfredi'', reaches . Both have triangular Pectoral fin#AnchPectoral, pectoral fins, horn-shaped cephalic fins and large, forward-facing mouths. They are classified among the Myliobatiformes (stingrays and relatives) and are placed in the Family (biology), family Myliobatidae (eagle rays). They have the largest brains and brain to body ratio of all fish, and can pass the mirror test. Mantas are found in warm temperate, subtropical and tropical waters. Both species are Pelagic fish, pelagic; ''M. birostris'' Animal migration, migrates across open oceans, singly or in groups, while ''M. alfredi'' tends to be resident and coastal. They are filter feeders and eat large quantities of zooplankton, which they gather with their open mouths as they swim. However, research suggests that the majority of their die ...

Mobula
''Mobula'' is a genus of rays in the family Mobulidae that is found worldwide in tropical and warm, temperate seas. Some authorities consider this to be a subfamily of the Myliobatidae (eagle rays). Their appearance is similar to that of manta rays, which are in the same family, and based on genetic and morphological evidence, the mantas belong in ''Mobula'' (they are traditionally in their own genus ''Manta''). Species of this genus are often collectively referred to as "devil rays", "flying mobula", or simply "flying rays", due to their propensity for breaching, sometimes in a spectacular manner. These rays gather in groups and leap out of the surface into the air up to around two metres before splashing back into the water. Depending on the species, the devil rays can attain widths up to , the largest being second only to the manta rays in size, which can reach . Despite their size, little is known about the devil rays, much of it anecdotal; the manta rays are better known. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnhamia (devil Ray)
''Burnhamia'' is an extinct genus of devil ray from the Paleogene period. Due to superficial similarities, some species were originally mistaken for Cow-nose rays and placed in the genus '' Rhinoptera''. It is known exclusively from dental batteries, mostly isolated teeth. There are several species attributed to this genus but their relation to each other is still unresolved. Some have proposed the type species ''B. daviesi'' arises in the late Paleocene and persists until the middle Eocene giving rise to the similar genus '' Eoplinthicus'' with an earlier offshoot leading to smaller and less ornamented species in the lower Eocene, namely ''B. fetahi''.Ebersole, Jun & Cicimurri, David.

Paramobula
''Paramobula'' is an extinct genus of ray in the family Myliobatidae (eagle rays). The genus was erected by Pfeil in 1981 to accommodate a fossil species first described from a number of teeth with distinctive characteristics found in the Chandler Bridge Formation in South Carolina. The species was originally described by Cappetta in 1970 as ''Manta fragilis'' but differed significantly from other ''Manta'' species. ''Paramobula fragilis'' dates back to the late Oligocene The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the .... References {{Taxonbar, from=Q7135269 Myliobatidae Fossil taxa described in 1970 ...

Myliobatiformes
Myliobatiformes () is one of the four orders of batoids, cartilaginous fishes related to sharks. They were formerly included in the order Rajiformes, but more recent phylogenetic studies have shown the myliobatiforms to be a monophyletic group, and its more derived members evolved their highly flattened shapes independently of the skates. Classification Nelson's ''Fishes of the World'' arranges the Myliobatiformes as: *Suborder Platyrhinoidei **Family Platyrhinidae (thornbacks) *Suborder Zanobatoidei **Family Zanobatidae (panrays) *Suborder Myliobatoidei ( stingrays) **Superfamily Hexatrygonoidea ***Family Hexatrygonidae (sixgill stingray) **Superfamily Urolophoidea ***Family Plesiobatidae (deepwater stingray) ***Family Urolophidae (round stingrays) **Superfamily Urotrygonoidea ***Family Urotrygonidae (American round stingrays) **Superfamily Dasyatoidea ***Family Dasyatidae (whiptail stingrays) ***Family Potamotrygonidae (river stingrays) ***Family Gymnuridae The bu ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thailand
Thailand ( ), historically known as Siam () and officially the Kingdom of Thailand, is a country in Southeast Asia, located at the centre of the Indochinese Peninsula, spanning , with a population of almost 70 million. The country is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the extremity of Myanmar. Thailand also shares maritime borders with Vietnam to the southeast, and Indonesia and India to the southwest. Bangkok is the nation's capital and largest city. Tai peoples migrated from southwestern China to mainland Southeast Asia from the 11th century. Indianised kingdoms such as the Mon, Khmer Empire and Malay states ruled the region, competing with Thai states such as the Kingdoms of Ngoenyang, Sukhothai, Lan Na and Ayutthaya, which also rivalled each other. European contact began in 1511 with a Portuguese diplomatic mission to Ayutthaya, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...
