In the Baltic States and Belarus, the Middle Devonian period is characterised by an abundant fossil record of invertebrates such as scolecodonts, brachiopods, ostracods, trilobites, bivalves, crinoids, gastropods, and tentaculites. On the other hand, there was limited diversity in the conodont and other vertebrate fauna. In this study, we introduce...

Milaičiai-103 borehole is located in the southwestern part of Lithuania. Stratigraphically, the core of Milaičiai-103 is represented by rocks from the Pridoli, Upper Silurian. Previous research examining conodont and brachiopod fossil material from Milaičiai-103 revealed a new "Šilalė Event" extinction (Spiridonov et al., 2020). In this study, we f...

The distribution of Silurian rocks in Lithuania is a good example of multifacial sediments with a marine deep shelf in the western part and a marine shallow shelf and lagoonal in the eastern and easternmost parts (Valiukevičius 2005). Meanwhile, the studied Milaičiai 103 well is located in the transition from open to deep shelf in the southwestern...

The Lusitanian Basin is located in the western part of Portugal (mainland), which was formed during the opening of the North Atlantic Ocean in the beginning of the Mesozoic Era. The geological cross section of this basin is reached approximately 5-6 km in thickness and consists of Upper Triassic to Lower Cretaceous sedimentary deposits. The infill...

Permian fishes and their isolated microremains are known from many localities in the Zechstein Basin. However, up to date the vertebrates have never been revealed in the southeasternmost part of this ancient sea. The new material consists of euselachian-type dermal denticles,?Listracanthus sp. dermal denticle,?Omanoselache sp. tooth, actinopterygia...

One of the most resourceful technics used by virtual palaeontology is the fossils studying through three-dimensional digital visualisation based on the multiply two-dimensional images obtained at various viewpoints. One of the most remarkable methods is considered to be a photogrammetry. It is a method for determining the 3D surface topography of a...

The poster is explaining how Micro-CT scan and 3D modeling can help to recognize non-visible fossils inside the rock based on the Late Jurassic fish remains from Torres Vedras (western Portugal).

For the last 20 to 25 years, Torres Vedras has been the scene of a crucial, vast and diverse number of fossil vertebrate occurrences. Bony fish are part of this important collection. Here we present a set of 64 Pycnodontiformes indet. specimens, comprising isolated and partially articulated vomerine and prearticular teeth, collected on the surface...

The late Permian time was a transformative period before the most severe mass extinction known. Even though fishes constitute a key component of marine ecosystems since the Silurian, their biogeographic patterns during the late Permian are currently insufficiently known. The new ichthyofaunal material described here comes from the southeastern part...

The International Meetings of Early-stage Researchers in Palaeontology (IMERP) are aimed at early-stage palaeontologists, from undergraduate students to recent post-doctoral researchers. Geologists, biologists or any scientist with research topics related to palaeontology, as well as palaeoartists, are also welcome. The IMERP has two main objective...

The late Permian was a transformative time, which ended with one of the most significant extinction events in Earth's history. Fish assemblages are a major component of marine food webs. The macroevolution and biogeographic patterns of late Permian fish are currently insufficiently known. In this contribution, a late Permian ichthyofauna from the K...

The assemblage of rare fish microremains of chondrichthyans and actinopterygians from Upper Permian de pos its in Karpėnai Quarry in northern Lithuania is described in detail for the first time. The deposits are characterized as reflecting a rapid phase of deposition of the Zechstein Limestone, in terpreted as on a shallow shelf above storm-wave ba...

The assemblage of rare fish microremains of chondrichthyans and actinopterygians from Upper Permian deposits in Karpėnai Quarry in northern Lithuania is described in detail for the first time. The deposits are characterized as reflecting a rapid phase of deposition of the Zechstein Limestone, interpreted as on a shallow shelf above storm-wave base...

New data on the Upper Homerian and Ludlow (Silurian) stratigraphy of the shallow water sedimentary and biotic succession of the Lithuanian part of the Silurian Baltic basin are presented here based on detailed analysis of the Vilkaviškis-134 core. Four formations: the Riga, Gėluva and Širvinta formations of Wenlock age and the Neris Formation of Lu...
