The last two decades have seen a remarkable increase in the known diversity of basal avialans and their paravian relatives. lack resolution relationships these groups combined with attributing behavior specialized taxa to base Paraves has clouded interpretations origin avialan flight. Here, we describe Hesperornithoides miessleri gen. et sp. nov., new theropod from Morrison Formation (Late Jurassic) Wyoming, USA, represented by single adult or subadult specimen comprising partial,...
Giant ichthyosaurs with body length estimates exceeding 20 m were present in the latest Triassic of UK. Here we report on discovery a second surangular from lower jaw giant ichthyosaur Somerset, The new find is comparable size and morphology to specimen Lilstock, described 2018, but it more complete better preserved. Both finds are uppermost Westbury Mudstone Formation (Rhaetian), comes Blue Anchor, approximately 10 km west along coast Lilstock. would have been >2 long, an individual...
We describe a new species of Lower Jurassic (Hettangian/Sinemurian–Pliensbachian) ichthyosaur, Ichthyosaurus anningae, sp. nov., from west Dorset, England, U.K. The holotype I. anningae (DONMG:1983.98), at least subadult, is the lower Pliensbachian Stonebarrow Marl Member (Charmouth Mudstone Formation). It most complete ichthyosaur known this time interval worldwide. assigned to on basis humerus, forefin, and pectoral girdle morphologies. Diagnostic features include short, robust humerus...
Abstract All specimens of Ichthyosaurus from the Lower Jurassic Somerset were previously identified as I. communis , an abundant and extremely variable species. Here, two new species are recognized multiple specimens. The assigned to on basis humerus, pectoral girdle forefin morphologies. larkini sp. nov. is distinguished by a broad jugal with blunt anterior end that extends far forward middle external naris, separating maxilla lacrimal; unique combination other features. somersetensis...
A 9.7 m long trackway was discovered in a plattenkalk quarry near the village of Wintershof, Bavaria, Germany, 2002. The huge ichnofossil derives from Lower Tithonian, Upper Jurassic Solnhofen Lithographic Limestone. is complete beginning to end and consists footprints, telson drag impressions, prosoma imprints identified as ichnotaxon Kouphichnium isp. Preserved at very specimen Mesolimulus walchi confirming mortichnia (death march). Trackways trace makers preserved together fossil record...
The largest reported ichthyosaurs lived during the Late Triassic (~235-200 million years ago), and isolated, fragmentary bones could be easily mistaken for those of dinosaurs because their size. We report discovery an isolated bone from lower jaw a giant ichthyosaur latest Lilstock, Somerset, UK. It documents that persisted well into Rhaetian Stage, close to time extinction event. This specimen has prompted reinterpretation several large, roughly cylindrical (Rhaetian Stage) Westbury...
Thousands of ichthyosaurs have been discovered from the rich Lower Jurassic deposits UK, with majority collected along Lyme Regis-Charmouth area Dorset coast. Here, I describe a new leptonectid ichthyosaur, Wahlisaurus massarae gen. et sp. nov., based on partial skull and an incomplete skeleton (Hettangian) Nottinghamshire, England. can be referred to Leptonectidae through possession extremely slender delicate snout, mandible shorter than snout which produces overbite. This referral is...
Ichthyosaur fossils are abundant in Lower Jurassic sediments with nine genera found the UK. In this paper, we describe partial skeleton of a large ichthyosaur from (lower Sinemurian) Warwickshire, England, which was conserved and rearticulated to form centrepiece new permanent gallery at Thinktank, Birmingham Science Museum 2015. The unusual three-dimensional preservation specimen permitted computed tomography (CT) scanning individual braincase elements as well entire reassembled skull. This...
A rediscovered collection of scientifically significant eurypterid fossil specimens, assigned to Slimonia acuminata and Erettopterus bilobus, is held in the Doncaster Museum Art Gallery. The specimens are from historically important late Silurian Lesmahagow inlier Lanarkshire, Scotland described herein. material ranges partial complete with a wide range size both genera. Most have either no or minimal damage. Some interesting features include orientation preservation eurypterids.
The validity of the parvipelvian ichthyosaur genus Protoichthyosaurus was evaluated by examining type material and recently recognized specimens. has a wide forefin with at least five primary digits, an anterior digital bifurcation in forefin, humerus that is nearly equal width distally proximally, coracoid well-developed posterior notches, features it shares more common Ichthyosaurus. Previously, synonymized Ichthyosaurus because incomplete understanding variation latter taxon. However,...
Ichthyosaurus communis De la Beche & Conybeare, Citation1821 and I. intermedius Citation1822 have been considered synonymous by some researchers, but distinct species others. The distinction between the two was originally based on tooth morphology, which has shown to vary ontogenetically as well within an individual. Subsequent literature of nineteenth century did not propose adequate diagnostic features distinguish species. In addition, illustrations suggest that both were confused with...
Abstract An ichthyosaur in the collections of Sedgwick Museum, Cambridge (CAMSMX.50187) was collected nineteenth century by renowned fossil collector Mary Anning, but has never been adequately described literature. As an Anning specimen, it is certainly from Lower Jurassic Lyme Regis, west Dorset. The near complete presacral skeleton lying on its left side and includes a skull, one partial forefin, pectoral bones, all six elements pelvic girdle, both hindfins. centra anterior caudal region,...
—Ichthyosaurus conybeari is a rare species, previously known only from an incomplete holotype and one referred specimen, both the Lyme Regis area of west Dorset coast, U. K. A newly recognized, nearly complete specimen (NMW 93.5G.2) first occurrence species in Somerset, revised diagnosis recognizes new morphological characters that distinguish species: slender maxilla with long, delicate premaxillary process; narrow postorbital; humerus anteriorly offset dorsal process has well-defined lip...
Abstract Early Cretaceous ichthyosaurs were globally distributed pelagic marine reptiles, but many remains are fragmentary, creating a Northern Hemisphere diversity bias. A rich Hauterivian locality near the Tyndall Glacier inside Torres del Paine National Park in southern Chile yields important new data regarding ichthyosaurian along Pacific margin of Gondwana. These will contribute to clarifying questions ichthyosaur taxonomy and palaeobiogeographical relationships between Gondwanan groups...
A formerly undescribed Ichthyosaurus specimen from the collection of Niedersächsisches Landesmuseum (Lower Saxony State Museum) in Hannover, Germany, provides valuable new information.The skeleton was collected Lower Jurassic strata (lower Hettangian, Blue Lias Formation) Doniford Bay, Somerset, UK.However, is a composite as almost entire tail has been added and other parts are reconstructed.Regardless incomplete preservation, estimated total length this individual, based on skull precaudal...
Abstract The abundance of specimens Ichthyosaurus provides an opportunity to assess morphological variation without the limits a small sample size. This research evaluates and taxonomic utility hindfin morphology. Two seemingly distinct morphotypes mesopodium occur in genus. Morphotype 1 has three elements third row: metatarsal two, distal tarsal four. is common morphology breviceps , I. conybeari somersetensis . 2 four row, owing bifurcation. morphotype occurs at least some each species,...
Open Access (OA) describes the free, unrestricted access to and re-use of published research articles.Recently, announcement 'Plan S' has catalysed a new wave interest, debate, practice surrounding OA.Here, we provide simple overview 'OA status' palaeontology journals within this rapidly shifting landscape.In particular, focus on aspects such as whether or not there are author-facing charges for Access, what embargo periods restrictions 'self-archiving' policies in place, sharing preprints...
The holotype of Wahlisaurus massarae is known only from a partial skull and postcranial skeleton the Lower Jurassic, collected near Normanton on Soar, Nottinghamshire, UK. It diagnosed relative to other ichthyosaurs basis autapomorphies coracoid unique combination characters. Here, we report second specimen W. . new comprises practically complete right that clearly shows morphology This was in situ quarry Somerset, base Blue Lias Formation, which corresponds Triassic–Jurassic boundary...
