Unknown until recently in the fossil record of Slovenia, many specimens of thylacocephalans were collected from the Middle Triassic (Anisian) beds of the Velika Planina Member and Strelovec Formation in Kamnik-Savinja Alps, as well as in the Late Triassic beds (Carnian) of the Martuljek Formation in the Julian Alps.

In the Kamnik-Savinja Alps (Slovenia), the Lower Serla Dolomite laterally passes into a succession of thin- to medium-bedded bituminous limestones of the Velika planina member. The finely laminated lower part of this member contains well-preserved actinopterygian fish and sauropterygian remains. The research aimed to determine the sedimentological...

Xiphosura are a group of marine euchelicerates with a fossil record spanning the majority of the Phanerozoic. Despite this longevity, horseshoe crab fossils are uncommon. This rarity is a result of their cuticular exoskeleton that limits the preservational potential of xiphosurid specimens. Nonetheless, a xiphosurid evolutionary radiation is record...

Upper Triassic limestones at Kozja dnina in the Julian Alps have long been known to yield an exceptionally preserved Carnian fauna. In the present study, we discuss three specimens of polychelidan lobsters found on bedding planes of platy limestones during recent years. Polychelidan lobsters have a very patchy fossil record and every new specimen i...

Abstract Background: To determine whether the presence of two palatal roots in permanent maxillary molars (PMMs) could be predicted by observing dental morphological traits during the clinical examination. Materials and method: A total of 18 second and 26 third PMMs with two palatal roots (2PR) were examined from the collection of extracted teeth....

Paleontologists have known the laminated platy limestones from Kozja dnina since the beginning of the 20th century. Th e locality is situated in the Vrata valley in the Julian Alps at an altitude of approximately 1,200 m. The exposed beds of grey thin laminated limestones were deposited in the oxygen-depleted deep-water marine environment, likely a...

The area of Tunjice Hills is well-known for the abundance of Miocene fossils. Early and Middle Miocene beds were investigated by Austro-Hungarian geologists and amateur naturalists from the early 19th century onwards (Bittner, 1884). Important new discoveries of well-preserved insects and fossil seahorses were made in the last decades (Žalohar et a...

In the last decade, a number of enthusiast Slovenian palaeontologists have researched Triassic horizons and discovered numerous previously unknown fossil localities with Middle and Late Triassic of Slovenian Alps. Well preserved plant, mollusc, decapod, brachiopod, echinoid, ophiuroid, crinoid, amphibian, fish, and reptile remains were found in the...

Xiphosurida—crown group horseshoe crabs—are a group of morphologically conservative marine chelicerates (at least since the Jurassic). They represent an idealised example of evolutionary stasis. Unfortunately, body fossils of horseshoe crabs seldom preserve appendages and their associated features; thus, an important aspect of their morphology is a...

Horseshoe crabs are an archetypal chelicerate group with a fossil record extending back to Early Ordovician time. Although extensively studied, the group generally has a low diversity across the Phanerozoic Eonothem. Here, we expand the known diversity of true horseshoe crabs (Xiphosurida) by the description of a new taxon from the Middle Triassic...

This doctoral thesis highlights epidemiological, anatomical, diagnostic, clinical and broad biomedical aspects of the permanent maxillary molars (PMMs) with a supernumerary palatal root (SPR). In the first study, we examined the external morphology of 44 PMM (18 second and 26 third PMMs) with SPR and a reference sample of 44 PMMs with one palatal r...

Osteosclerotic lesions are a common finding on dental radiographs. They are considered developmental variants of a normal bone architecture and they usually do not need any treatment. The purpose of this article is to present a rare case of osteosclerotic lesion of the mandible causing trigeminal neuropathy by compression of the alveolar nerve. The...

''Pokaži mi svoje zobe in povedal ti bom kdo si?'' Georges Cuvier (1769-1832) Zobje nedvomno sodijo med pomembnejše evolucijske pridobitve, saj živalim in človeku omogočajo učinkovitejše pridobivanje in predelavo hrane. Evolucija zobnega organa je dosegla največjo kompleksnost in raznolikost pri sesalcih, vendar se zgodba o zobeh začne že veliko...

Podatki iz literature kažejo, da se nadštevilna palatinalna korenina (NPK) najpogosteje razvije pri tretjem zgornjem kočniku, najmanj pogosto pri prvem zgornjem kočniku. V endodontiji se z NPK največkrat srečamo pri drugem zgornjem kočniku, ki ima po p...

The permanent maxillary molars (PMM1, 2, 3) occasionally possess 2 palatal (P) roots. One of them is the regular P root that is always present; the other is a supernumerary P root (SPR). Literature data indicate that the SPR occurs least frequently on PMM1. Peikoff et al. (1996), Libfeld and Rotstein (1989) and Matsumoto (1986) reported the prevale...

The majority of permanent mandibular first molars (PMFM) possess 2 roots: one mesial and one distal root. Occasionally, there is an additional distolingual root named radix entomolaris (RE) (Figure A). The length of the RE is variable; however, those shorter than half of the length of the distal root represent a minority of all cases (Song et al.,...
