Haenamichnus
''Haenamichnus'' is an ichnogenus that has been attributed to azhdarchid pterosaurs. In 2002, paleontologists Koo-Geun Hwang, Min Huh, Martin Lockley, David Unwin and Joanna Wright named the type species ''Haenamichnus uhangriensis'', based on fossil tracks they found in the Uhangri Formation of South Korea, dating to 81 to 79 million years ago during the Campanian. The largest track may have belonged to an individual reaching in wingspan, in height and in body mass. A second species, ''H. gainensis'', was discovered from the Haman Formation, but is now considered a bipedal crocodylomorph track reassigned to as '' Batrachopus'' cf. ''grandis''.

List Of Pterosaurs
This list of pterosaurs is a comprehensive listing of all genera that have ever been included in the order Pterosauria, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomen dubium''), or were not formally published ('' nomen nudum''), as well as junior synonyms of more established names, and genera that are no longer considered pterosaurian. The list currently includes 263 genera. Scope and terminology There is no official, canonical list of pterosaur genera, but the most thorough attempts can be found at the Pterosauria section of Mikko Haaramo's ''Phylogeny Archive'', the Genus Index at Mike Hanson's ''The Pterosauria'', supplemented by the Pterosaur Species List, and in the fourth supplement of Donald F. Glut's ''Dinosaurs: The Encyclopedia'' series. Authors and year The authors column lists the authors of the formal description responsible for the erection of the genus listed ...

Pterosaurs
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haman Formation
The Haman Formation () is an Early Cretaceous geological formation in South Korea. It has been dated to the Albian, with an estimated maximum depositional age of 105.4 ± 0.4 Ma. The deposit is known for its tracks, including those of dinosaurs, pterosaurs and birds. It overlies the Silla Conglomerate which overlies the Chilgok Formation. It is laterally equivalent to the Sagog Formation. Vertebrate paleofauna Fossil pterosaur, theropod, sauropod and ornithopod tracks have been recovered from this formation. Some dinosaur tracks show signs of display behavior. Dinosaur skin impressions have also been found in this formation.

Timeline Of Pterosaur Research
This timeline of pterosaur research is a chronologically ordered list of important fossil discoveries, controversies of interpretation, and taxonomic revisions of pterosaurs, the famed flying reptiles of the Mesozoic era. Although pterosaurs went extinct millions of years before humans evolved, humans have coexisted with pterosaur fossils for millennia. Before the development of paleontology as a formal science, these remains would have been interpreted through a mythological lens. Myths about thunderbirds told by the Native Americans of the modern Western United States may have been influenced by observations of ''Pteranodon'' fossils. These thunderbirds were said to have warred with water monsters, which agrees well with the co-occurrence of ''Pteranodon'' and the ancient marine reptiles of the seaway over which it flew. The formal study of pterosaurs began in the late 18th century when naturalist Cosimo Alessandro Collini of Mannheim, Germany published a description of ...

Campanian
The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian. The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks. Etymology The Campanian was introduced in scientific literature by Henri Coquand in 1857. It is named after the French village of Champagne in the department of Charente-Maritime. The original type locality was a series of outcrop near the village of Aubeterre-sur-Dronne in the same region. Definition The base of the Campanian Stage is defined as a place in the stratigraphic column wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Lockley
Martin G. Lockley (born 1950) is a Welsh palaeontologist. He was educated in the United Kingdom where he obtained degrees (BSc and PhD) and post-doctoral experience in Geology in the 1970s.

Ichnogenus
An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. ''Ichnotaxa'' comes from the Greek ίχνος, ''ichnos'' meaning ''track'' and ταξις, ''taxis'' meaning ''ordering''.Definition o'ichno'at dictionary.com. Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils. They are assigned genus and species ranks by ichnologists, much like organisms in Linnaean taxonomy. These are known as ichnogenera and ichnospecies, respectively. "Ichnogenus" and "ichnospecies" are commonly abbreviated as "igen." and "isp.". The binomial names of ichnospecies and their genera are to be written in italics. Most researchers classify trace fossils only as far as the ichnogenus rank, based upon trace fossils that resemble each other in morphology but have subtle differences. Some authors have constructed detailed hierarchies up to ichnosupe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azhdarchid
Azhdarchidae (from the Persian word , , a dragon-like creature in Persian mythology) is a family of pterosaurs known primarily from the Late Cretaceous Period, though an isolated vertebra apparently from an azhdarchid is known from the Early Cretaceous as well (late Berriasian age, about 140 million years ago). Azhdarchids included some of the largest known flying animals of all time, but smaller cat-size members have also been found. Originally considered a sub-family of Pteranodontidae, Nesov (1984) named the Azhdarchinae to include the pterosaurs ''Azhdarcho'', ''Quetzalcoatlus'', and ''Titanopteryx'' (now known as ''Arambourgiania''). They were among the last known surviving members of the pterosaurs, and were a rather successful group with a worldwide distribution. By the time of the end-Cretaceous mass extinction, most pterosaur families except for the Azhdarchidae disappear from the fossil record, but recent studies indicate a wealth of pterosaurian fauna, including pteran ...
