The site documents a fauna of Early Jurassic nektonic marine animals (five species of fishes, one species of marine crocodilian, two species of ichthyosaurs, cephalopods and crustaceans), but also over 20 spe- cies of insects. Unlike other fossil sites of similar age, the 3D preservation at Strawberry Bank provides unique evidence on palatal and braincase structures in the fishes and reptiles. The age of the site is important, documenting a marine ecosystem during recovery from the end-Triassic mass extinction, but also exactly coincident with the height of the Toarcian Oceanic Anoxic Event, a further time of turmoil in evolution.

    Osteology and phylogeny of Late Jurassic ichthyosaurs from the Slottsmøya Member Lagerstätte (Spitsbergen, Svalbard) LENE L. DELSETT, AUBREY J. ROBERTS, PATRICK S. DRUCKENMILLER, and JØRN H. HURUM Delsett, L.L., Roberts, A.J., Druckenmiller, P.S., and Hurum, J.H. 2019. Osteology and phylogeny of Late Jurassic ichthyosaurs from the Slottsmøya Member Lagerstätte (Spitsbergen, Svalbard). Acta Palaeontologica Polonica 64 (4): 717–743. Phylogenetic relationships within the important ichthyosaur family Ophthalmosauridae are not well established, and more specimens and characters, especially from the postcranial skeleton, are needed. Three ophthalmosaurid specimens from the Tithonian (Late Jurassic) of the Slottsmøya Member Lagerstätte on Spitsbergen, Svalbard, are described. Two of the specimens are new and are referred to Keilhauia sp. and Ophthalmosauridae indet. respectively, whereas the third specimen consists of previously undescribed basicranial elements from the holotype of Cryopterygius kristiansenae. The species was recently synonymized with the Russian Undorosaurus gorodischensis, but despite many similarities, we conclude that there are too many differences, for example in the shape of the stapedial head and the proximal head of the humerus; and too little overlap between specimens, to warrant synonymy on species level. A phylogenetic analysis of Ophthalmosauridae is conducted, including all Slottsmøya Member specimens and new characters. The two proposed ophthalmosaurid clades, Ophthalmosaurinae and Platypterygiinae, are retrieved under some circumstances, but with lit- tle support. The synonymy of three taxa from the Slottsmøya Member Lagerstätte with Arthropterygius is not supported by the present evidence.

We describe a suite of ichthyosaur fossils from the Early to Middle Jurassic of Skye, which to our knowl- edge are the first ichthyosaurs from Scotland to be described and figured in detail. These fossils span approximately 30 mil- lion years, from the Sinemurian to the Bathonian, and indicate that ichthyosaurs were a major component of Scottish marine faunas during this time.

However, some genera are known from only partial skeleton and many characters are coded as “?” (Table 1S). Therefore, we provide two analyses in the text based on different combinations of ingroup taxa. In the first analysis, all the taxa in Table 1S are included and results in many polytomies. In the second analysis, the taxa which can not be coded for more than 1/3 (54.3 characters) are removed and the topology is highly resolved. Table S1.

    First Report of Leptonectes (Ichthyosauria: Leptonectidae) from the Lower Jurassic (Pliensbachian) of Asturias, Northern Spain

    Palaeontologia Electronica palaeo-electronica.org First report of Leptonectes (Ichthyosauria: Leptonectidae) from the Lower Jurassic (Pliensbachian) of Asturias, northern Spain Marta S. Fernández, Laura Piñuela, and José Carlos García-Ramos ABSTRACT Early Jurassic ichthyosaurs are well-known based on the abundant and exqui- sitely preserved European records of the Western Tethys. For example, faunas from Southern England and the Toarcian Posidonia shales of Holzmaden and surrounding areas (Germany) are known worldwide. However, between these areas there are still gaps and/or under-sampled localities from the northern coast of Europe. In recent years as a result of systematic palaeontological and geological explorations of Pliens- bachian fossiliferous localities along the coast of Asturias (northern Spain), ichthyosaur specimens have been collected. One of them can be identified at lower taxonomic lev- els and it is referred to Leptonectes sp. These new findings highlight the richness of the fossil record of the northern coast of Spain and suggest that the abundance of Pliens- bachian ichthyosaurs worldwide may have been underestimated.
