Paleontology
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intertrappean Beds
The Intertrappean Beds are a Late Cretaceous and early Paleogene geologic unit in India. These beds are found as interbeds between Deccan Traps layers, including the slightly older Lameta Formation. They consist a number of different subgroups and formations, and span the Cretaceous–Paleogene boundary. Many mostly fragmentary fossils, especially of small vertebrates, are known from the formation. Indeterminate theropod and pterosaur remains have been recovered from the formation, as well as dinosaur eggs.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. The mammal genera '' Deccanolestes'', '' Sahnitherium'', '' Bharattherium'', '' Indoclemensia, Indotriconodon'' and'' Kharmerungulatum'' have been recovered from several localities. The Early Eocene-aged Bamanbor locality in Gujarat preserves articulated freshwater fish specimens. A rich plant flora is known from the formation. Stratigraphy Although often thought of as a contemporaneous unit that was for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent 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, Aus ...

Indotriconodon
''Indotriconodon magnus'' is an extinct mammal from the Late Cretaceous of India. A eutriconodont, it represents the geologically youngest of the group dating to the Maastrichtian just a few thousand years before the KT event (a record previously held by '' Alticonodon lindoei'' from the Campanian of Canada), as well as a relatively large sized Mesozoic mammal. Description ''Indotriconodon magnus'' is known only from a single lower molar. It is about 20% smaller than that of ''Repenomamus giganticus'' but larger than that of other eutriconodonts, making it a badger-sized mammal. Phylogeny In its 2024 description it nests deeply within Eutriconodonta, being sister taxa to Volaticotherini. Palaeoceology Found in the Intertrappean Beds, it co-existed with at least other ten mammal genera as well various squamates, turtles and dinosaur Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic Geological period, period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Vasuki Indicus
''Vasuki indicus'' is an extinct snake species in the family Madtsoiidae that lived during the Middle Eocene of what is now India. ''V. indicus'' is the Monotypic taxon, only species in the genus ''Vasuki'', known from several vertebrae found in the Naredi Formation. It has an estimated body length between , making it the largest known madtsoiid. The highest length estimates place ''Vasuki'' among the longest snakes ever discovered. Discovery and naming The holotype specimen of ''Vasuki'', IIT Roorkee, IITR/VPL/SB 3102-1-21, was discovered in 2005 within the sedimentary layers of the Naredi Formation in the Panadhro Lignite Mine in the Kutch district of Gujarat State, western India. The specimen consists of 27 pre-cloacal vertebrae, some of which were found in Joint, articulation. The fossil material was found some time after 2004, and preliminary analyses suggested crocodilian affinities for the fossil material without further review. In 2024, ''Vasuki indicus'' was Species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
