Palaeoecology and palaeoenvironment of the Aquitanian locality Ulm-Westtangente (MN2, Lower Freshwater Molasse, Germany)
Swiss Journal of Palaeontology - Tập 131 - Trang 183-199 - 2011
The mammalian fauna of the German locality Ulm-Westtangente from the Aquitanian Lower Freshwater Molasse is investigated. The fauna is compared to other rich European localities of the same time period. It is shown to be one of the richest localities for fossil mammals and brings interesting insights into the composition of the Aquitanian European faunas. Sixty-one species are identified and high ......
A redescription of Trachelosaurus fischeri from the Buntsandstein (Middle Triassic) of Bernburg, Germany: the first European Dinocephalosaurus-like marine reptile and its systematic implications for long-necked early archosauromorphs
Swiss Journal of Palaeontology - - 2024
Some of the earliest members of the archosaur-lineage (i.e., non-archosauriform archosauromorphs) are characterised by an extremely elongated neck. Recent fossil discoveries from the Guanling Formation (Middle Triassic) of southern China have revealed a dramatic increase in the known ecomorphological diversity of these extremely long-necked archosauromorphs, including the fully marine and viviparo......
The nature of the platyceratid–crinoid association as revealed by cross-sectional data from the Carboniferous of Alabama (USA)
Swiss Journal of Palaeontology - Tập 137 - Trang 177-187 - 2018
The association of Paleozoic crinoids and platyceratid gastropods has drawn the attention of paleontologists for nearly 200 years. It has been variably interpreted as predatory, commensalistic, mutualistic or parasitic. Previous cross-sectional analyses of large populations of crinoids and platyceratids have favored the parasitic explanation for the interaction because of data suggesting that the ......
An assessment of age determination in fossil fish: the case of the opercula in the Mesozoic actinopterygian Saurichthys

Ontogenetic variation in the cranium of Mixosaurus cornalianus, with implications for the evolution of ichthyosaurian cranial development
Swiss Journal of Palaeontology - Tập 142 - Trang 1-23 - 2023
Relatively complete ontogenetic series are comparatively rare in the vertebrate fossil record. This can create biases in our understanding of morphology and evolution, since immaturity can represent a source of unrecognized intraspecific variation in both skeletal anatomy and ecology. In the extinct marine reptile clade Ichthyopterygia, ontogenetic series were widely studied only in some Jurassic ......
‘Arm brains’ (axial nerves) of Jurassic coleoids and the evolution of coleoid neuroanatomy
Swiss Journal of Palaeontology - Tập 142 - Trang 1-22 - 2023
Although patchy, the fossil record of coleoids bears a wealth of information on their soft part anatomy. Here, we describe remains of the axial nerve cord from both decabrachian (Acanthoteuthis, Belemnotheutis, Chondroteuthis) and octobrachian (Plesioteuthis, Proteroctopus, Vampyronassa) coleoids from the Jurassic. We discuss some hypotheses reflecting on possible evolutionary drivers behind the n......
Giải phẫu hộp sọ số hóa của rùa Bắc Mỹ thời Oligocen Stylemys nebrascensis với các bình luận thuế tộc về loài và so sánh với các loài Testudinidae hiện tại thuộc clade Gopherus–Manouria Dịch bởi AI
Swiss Journal of Palaeontology - - 2024
Giải phẫu của các loài rùa Bắc Mỹ ít được hiểu biết, mặc dù có một hồ sơ hóa thạch phong phú từ thời Eocene và các tầng trẻ hơn. Stylemys nebrascensis là một loài rùa đáng chú ý trong vấn đề này, vì hàng trăm mẫu vật đã được biết đến từ các trầm tích Oligocen, và loài này là một trong những loài rùa hóa thạch đầu tiên được mô tả trong tài liệu khoa học. Kể từ khi mô tả ban đầu dựa trên một cái mai......

Caviomorph rodents from the Pampean region (Argentina) in the historical Santiago Roth Collection in Switzerland
Swiss Journal of Palaeontology - Tập 142 - Trang 1-14 - 2023
Here I reviewed the Pleistocene caviomorphs collected by Santiago Roth (collection from Catalog No. 5) and housed at the paleontological collection of the Paläontologisches Institut und Museum, Universität Zürich, Zurich (Switzerland). The fossils were found in Pleistocene strata from Buenos Aires and Santa Fé provinces (Argentina) during the late nineteenth century. The material includes cranioma......
First record of the enigmatic coleoid genus Longibelus from Sakhalin (Far East Russia): a contribution to our understanding of Cretaceous coleoid habitats in the Pacific Realm
Swiss Journal of Palaeontology - Tập 140 - Trang 1-8 - 2021
A newly collected specimen of the enigmatic coleoid genus Longibelus is recorded from lower Turonian strata along the River Shadrinka in Sakhalin (Russian Far East). To date, this is the first record of Late Cretaceous coleoid cephalopods from the island and, in fact, from the entire Pacific coast of the Russian Federation. Lithological characteristics, coupled with published geochemical analyses ......
