Abstract The collection and dissemination of vertebrate ichnological data is struggling to keep up with techniques that are becoming commonplace in the wider palaeontological field. A standard protocol required ensure recorded, presented archived a manner will be useful both contemporary researchers, future generations. Primarily, our aim make 3D capture practice, provide guidance on how such can communicated effectively (both via literature other means) openly perpetuity. We recommend data,...
Abstract This study concerns the formation, taphonomy, and preservation of human footprints in microbial mats present-day tidal-flat environments. Due to differences water content nature underlying sediment, a wide range footprint morphologies was produced by same trackmaker. Most true tracks are subjected modification due taphonomic processes, leading modified tracks. In addition formation biolaminites, play major role on tidal flats. A may be consolidated desiccation or lithification mat,...
Late Jurassic sauropod trackways from the Jura Mountains (NW Switzerland) and central High Atlas (Morocco) are described compared. Emphasis is put on track preservation trackway configuration. The similar with respect to pes manus outlines, but they show a large range of Only one reveals digit claw impressions, thus differences in gauge position tracks most explicit characters for their distinction. Early Cretaceous ichnotaxa Brontopodus, Parabrontopodus Breviparopus reviewed differential...
A new ichnospecies of a large theropod dinosaur, Megalosauripus transjuranicus, is described from the Reuchenette Formation (Early–Late Kimmeridgian, Late Jurassic) NW Switzerland. It based on very well-preserved and morphologically-distinct tracks (impressions) several trackways, including different preservational types tracksites horizons. All trackways were excavated along federal Highway A16 near Courtedoux (Canton Jura) systematically documented in field orthophotos laserscans. The...
Jurabrontes curtedulensis, a new ichnogenus and species of Late Jurassic giant theropod dinosaur track is described based on very well-preserved morphologically-distinct tracks, all carefully excavated along federal highway A16 (Canton Jura, NW Switzerland). All trackways were systematically documented including parameter measurements, descriptions, outline drawings, orthophotos laserscans. characterised by sub-equal length width, small anterior triangle, weak mesaxony, three blunt digits...
Background Minute to medium-sized (footprint length (FL) less than 30 cm) tridactyl dinosaur tracks are the most abundant in Late Jurassic tracksites of Highway A16 (Reuchenette Formation, Kimmeridgian) Jura Mountains (NW Switzerland). During excavations, two morphotypes, one gracile and robust, were identified field. Furthermore, large-sized theropod ichnospecies ( Megalosauripus transjuranicus Jurabrontes curtedulensis ) an ornithopod-like morphotype (Morphotype II) have recently been...
Re-examination of the sauropod dinosaur Cetiosauriscus greppini von Huene 1922 (Reuchenette Formation; Kimmeridgian, Late Jurassic) from northwestern Switzerland has revealed a well-preserved cartilage capsule at distal extremity right humerus. The represents hyaline together with fibrocartilage and can be distinguished by colour, surface structure histology periosteum bone. This is first fossil evidence for articular in sauropodomorph dinosaur. It indicates presence large on forelimbs,...
The orientation of the scapulocoracoid in sauropod dinosaurs is reconstructed based on comparative anatomical investigations pectoral girdles extant amniotes. In reconstruction proposed here, scapula sauropods stands at an angle least 55 degrees to horizontal plane mechanical coherence with sternal apparatus including coracoids. coracoids are oriented cranioventrally rib cage and glenoid directed mediolaterally, which allows humerus swing a sagittal plane. inclination for Diplodocus (60-65...
We present an update and a review of the Late Cretaceous dinosaur tracksites Bolivia. The Puca Group (Coniacian – Maastrichtian) records tracks trackways two different titanosaurid sauropods, ankylosaurs, hadrosaurs theropod groups from Central Andean lacustrine back arc basin. sites Maragua syncline (Chuquisaca) new data on famous Toro site (Potosi). Furthermore, first complete map world's largest tracksite, Cal Orck'o (El Molino Formation, Sucre) gives insight into behavior movement...
In 2002 a new dinosaur tracksite was discovered in calcareous laminites of early Late Kimmeridgian age along the future course "Transjurane" highway Courtedoux, Canton Jura, Northern Switzerland. The site has an extraordinary scientific potential, as laminites, which have been deposited intertidal to supratidal environment, contain at least 6 track-bearing levels total thickness about 1 m. are being systematically excavated by "Section de paleontologie" over area approximately 1500 m2. So...
Giant Middle Coniacian to Lower Campanian Platyceramus Seitz is among the largest Cretaceous bivalves, commonly reaching an axial length of over 1 m, and occasionally 2–3 m in size. The genus characterized by its large size, very low convexity, normal inflation limited mostly umbonal area, flattened flanks. It especially common moderately deep calcareous shale facies, as well chalks limestones Niobrara Formation equivalents. Preferred facies contain abundant pyrite, elevated total organic...
The Cal Orck'o tracksite is exposed in a quarry wall, approximately 4.4 km NW of Sucre (Department Chuquisaca, Bolivia) the Altiplano/Cordillera Oriental, El Molino Formation (Middle Maastrichtian). Fossiliferous oolitic limestones, associated with large, freshwater stromatolites and nine levels dinosaur tracks document an open lacustrine environment. main track-bearing level almost vertical surface area ~ 65,000 m 2 . high-resolution mapping site from 1998 to 2015 revealed total 12,092...
Fossil footprints are very widespread in the Late Paleozoic and Mesozoic rocks of eastern Utah, but until recently have not been studied detail. This is surprising light fact that skeletal remains fossils this area generally rare, whereas common informative about distribution behavior ancient vertebrates. In report we describe more than three dozen tracksites Glen Canyon National Recreation Area (GCNRA) immediate vicinity, from eight formations (Cedar Mesa, Moenkopi, Chinle, Wingate,...
The largest known sauropod trackway site from the Upper Jurassic in Europe has been found northern Jura Mountains of Switzerland. Since initial discovery 1988, detailed ichno‐facies mapping sites undertaken and completed. Six separate (from 5 to 45km apart) have located date; one, displaying 345 single imprints, extends over a surface 7000 m2. As all reported occur within same bed, these vertebrate prints form megatracksite covering an area more than 360 km2. All localities are...
Until now dinosaur tracks from Switzerland were only known Triassic and Late Jurassic strata. We report here for the first time occurrence of ornithopod Schrattenkalk Formation (Late Aptian) Swiss Central Alps. The locality is situated in an abandoned quarry on shore Lake Lucerne close to village Beckenried. steeply inclined surface has more than 50 (in three trackways) dinosaurs that are attributed iguanodontids. Three trackways can be followed distances 25 35 m. lengths footprints (mean:...
Trackways described as Batrachopus (Batrachopodidae Lull, 1904 R. S. 1904. Fossil footprints of the Jura-Trias North America. Memoirs Boston Society Natural History, 5: 461–557. [Google Scholar]) from Lower Jurassic Europe are rare and in some cases different type trackways Differences may be part attributable to preservation, but current evidence suggests that there is inherent variability Batrachopodidae morphotypes, beyond differential preservation. Type a stout-toed form, with minimal...
The pre-sacral vertebrae of most sauropod dinosaurs were surrounded by interconnected, air-filled diverticula, penetrating into the bones and creating an intricate internal cavity system within vertebrae. Computational finite-element models two cervical now demonstrate mechanical reason for vertebral pneumaticity. analyses show that structure leads to even distribution all occurring stress fields along vertebrae, concentrated mainly on their external surface laminae. regions between laminae...
