Serradraco
''Serradraco'' is a genus of Early Cretaceous pterodactyloid pterosaur from the Valanginian aged Tunbridge Wells Sand Formation in England. Named by Rigal ''et al.'' in 2018 with the description of a second specimen, it contains a single species, ''S. sagittirostris'', which was formerly considered a species of ''Lonchodectes'', ''L. sagittirostris''. In 2020, Averianov suggested it did not belong in Lonchodectidae. The second specimen, BEXHM 2015.18, consists of a small fragment of jaw with three teeth; six complete caudal vertebrae fused together and two fragmentary caudal vertebrae in articulation; a distal left ulna; a right proximal syncarpal; portions of a minimum of three phalanges and two indeterminate elements. Discovery and naming In 1874, Richard Owen named a pair of lower jaws from the collection of Samuel Husband Beckles, found at St Leonards-on-Sea in Sussex, as a new species of ''Pterodactylus'': ''Pterodactylus sagittirostris''. The specific name means "arrowhead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pterodactylus
''Pterodactylus'' (from Greek () meaning 'winged finger') is an extinct genus of pterosaurs. It is thought to contain only a single species, ''Pterodactylus antiquus'', which was the first pterosaur to be named and identified as a flying reptile. Fossil remains of ''Pterodactylus'' have primarily been found in the Solnhofen limestone of Bavaria, Germany, which dates from the Late Jurassic period (early Tithonian stage), about 150.8 to 148.5 million years ago. More fragmentary remains of ''Pterodactylus'' have tentatively been identified from elsewhere in Europe and in Africa. ''Pterodactylus'' was a generalist carnivore that probably fed on a variety of invertebrates and vertebrates. Like all pterosaurs, ''Pterodactylus'' had wings formed by a skin and muscle membrane stretching from its elongated fourth finger to its hind limbs. It was supported internally by collagen fibres and externally by keratinous ridges. ''Pterodactylus'' was a small pterosaur compared to other famo ...

Tunbridge Wells Sand Formation
The Tunbridge Wells Sand Formation is a geological unit which forms part of the Wealden Group and the uppermost and youngest part of the unofficial Hastings Beds. These geological units make up the core of the geology of the Weald in the English counties of West Sussex, East Sussex and Kent. The other component formations of the Hastings Beds are the underlying Wadhurst Clay Formation and the Ashdown Formation. The Hastings Beds in turn form part of the Wealden Group which underlies much of southeast England. The sediments of the Weald, including the Tunbridge Wells Sand Formation, were deposited during the Early Cretaceous Period, which lasted for approximately 40 million years from 140 to 100 million years ago. The Tunbridge Wells Sands are of Late Valanginian age.Hopson, P.M., Wilkinson, I.P. and Woods, M.A. (2010) ''A stratigraphical framework for the Lower Cretaceous of England''.

Lonchodectes
''Lonchodectes'' (meaning "lance biter") was a genus of lonchodectid pterosaur from several formations dating to the Turonian (Late Cretaceous) of England, mostly in the area around Kent. The species belonging to it had been assigned to ''Ornithocheirus'' until David Unwin's work of the 1990s and 2000s.Kellner, A.W.A. (2003). Pterosaur phylogeny and comments on the evolutionary history of the group: In: Buffetaut, E., and Mazin, J.-M. (Eds.). ''Evolution and Palaeobiology of Pterosaurs''. Geological Society Special Publication 217:105-137. 1-86239-143-2. Several potential species are known; most are based on scrappy remains, and have gone through several other generic assignments. The genus is part of the complex taxonomy issues surrounding Early Cretaceous pterosaurs from Brazil and England, such as ''Amblydectes'', ''Anhanguera'', ''Coloborhynchus'', and ''Ornithocheirus''.

Pterodactyloidea
Pterodactyloidea (derived from the Greek words ''πτερόν'' (''pterón'', for usual ''ptéryx'') "wing", and ''δάκτυλος'' (''dáktylos'') "finger" meaning "winged finger", "wing-finger" or "finger-wing") is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles. They appeared during the middle Jurassic Period, and differ from the basal (though paraphyletic) rhamphorhynchoids by their short tails and long wing metacarpals (hand bones). The most advanced forms also lack teeth, and by the late Cretaceous, all known pterodactyloids were toothless. Many species had well-developed crests on the skull, a form of display taken to extremes in giant-crested forms like ''Nyctosaurus'' and ''Tupandactylus''. Pterodactyloids were the last surviving pterosaurs when the order became extinct at the end of the Cretaceous Period, together with the non-avian dinosaurs and most marine reptiles. "Pteroda ...

Ornithocheirus
''Ornithocheirus'' (from Ancient Greek "ὄρνις", meaning ''bird'', and "χεῖρ", meaning ''hand'') is a pterosaur genus known from fragmentary fossil remains uncovered from sediments in the UK and possibly Morocco. Several species have been referred to the genus, most of which are now considered as dubious species, or members of different genera, and the genus is now often considered to include only the type species, ''Ornithocheirus simus''. Species have been referred to ''Ornithocheirus'' from the mid-Cretaceous period of both Europe and South America, but ''O. simus'' is known only from the UK, though a specimen referred to ''O.'' cf. ''simus'' is also known from Morocco. Because ''O. simus'' was originally named based on poorly preserved fossil material, the genus ''Ornithocheirus'' has suffered enduring problems of zoological nomenclature. Fossil remains of ''Ornithocheirus'' have been recovered mainly from the Cambridge Greensand of England, dating to the beginni ...

Reginald Walter Hooley
Reginald Walter Hooley (5 September 1865 – 5 May 1923) was a businessman and amateur paleontologist, collecting on the Isle of Wight. He is probably best remembered for describing the dinosaur ''Iguanodon atherfieldensis'', now ''Mantellisaurus.'' Biography Reginald Hooley was born on 5 September 1865 in Southampton, the son of William Hooley, a wealthy gentleman. In 1889 R.W. Hooley began to work for ''Godrich & Petman'', wine merchants, and later in life became managing director of that firm. Living in Portswood, in 1912 he married E.E. Holden and moved to Winchester. In 1913 he was elected a member of the Winchester city council. Hooley was a member of the Hampshire Field Club & Archaeological Society at Winchester from 1890. He was one of the founders of the Isle of Wight Natural History and Archaeological Society. He was an honorary curator of the Winchester Museum between 1918 and 1923.

Peter Wellnhofer
Peter Wellnhofer (born Munich, 1936) is a German paleontologist at the Bayerische Staatssammlung fur Paläontologie in Munich. He is best known for his work on the various fossil specimens of ''Archaeopteryx'' or "Urvogel", the first known bird. Wellnhofer's other work includes ''The Illustrated Encyclopedia of Pterosaurs'' from 1991. ''Wellnhoferia'', a bird closely related to ''Archaeopteryx'', or a species of the Urvogel itself, was named in his honour in 2001. The pterosaur ''Wellnhopterus'' was named in his honour in 2021. In 2007 a special meeting of pterosaur experts in Munich was dedicated to Wellnhofer, describing him as "the foremost authority on pterosaurs for the last four decades." The meeting produced a festschrift In academia, a ''Festschrift'' (; plural, ''Festschriften'' ) is a book honoring a respected person, especially an academic, and presented during their lifetime.

David Unwin
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David c ...

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...
