Opis:
An incomplete tooth-crown showing the features characteristic of marine crocodylomorphs of the family Metriorhynchidae has been found in glauconitic marls from the uppermost Callovian/lowermost Oxfordian of Ogrodzieniec, situated in the southern part of the Cracow-Czestochowa Upland. The precise taxonomic identification is not possible, but to date only the genus Metriorhynchus has been known from the Callovian. This is the first evidence of Metriorhynchidae in the Cracow-Czestochowa Upland (Polish Jura Chain).

Opis:
The present article concerns a characteristics of enigmatic encrusting organisms of the order Microconchida (microconchids), similar to polychaetes of the genus Spirorbis, as well as a description of their finds from the Upper Carboniferous of the Upper Silesia region, southern Poland. The microconchids described here may represent the genus Microconchus. Most of the individuals encrust terrestrial flora and bivalve shells, and thus they certainly inhabited freshwater or, at most, brackish water environment. Similarly as the Recent polychaetes of the genus Spirorbis, the microconchids described here occur in association composed of both adult and juvenile individuals. The juveniles, however, dominate, what may indicate they have died due to some stress conditions (high rate of deposition and/or low oxygen content in the water). The microconchids are poorly-preserved. The original calcitic mineralogy of their tubes was replaced by phases similar to lead sulfide and dolomite.

Opis:
The problemof application of pyrite framboids in reconstructions of the redox conditions is presented. The characteristics of pyrite framboids, their origin and principles of application in paleoenvironmental interpretations are given. The pyrite framboid diameter distribution as indicators of redox conditions was presented on the examples of the Middle Jurassic (Upper Bajocian-Lower Bathonian) ore-bearing clays of the Polish Jura, and Upper Devonian (Middle and Upper Famennian) dark grey and black shales from Kowala (Holy Cross Mountains). It has been shown, that during the sedimentation of the ore-bearing clays, the pyrite framboids formed in the sediment, below the oxic water column; however, some episodic oscillation around the dysoxic conditions cannot be entirely excluded. During the sedimentation of the Middle Famennian dark grey shales, the redox conditions at the sea-floor oscillated around dysoxia. In both examples, the framboids are characterized by wide range of their diameters and the presence of large, >10 "my"m, framboids. On the contrary, the Upper Famennian black shales, representing the Hangenberg event, were deposited below the euxinic conditions in the water column. It is indicated by a high frequency of small-size framboids, far below 6 "my"m in diameter, and the lack of the large ones. The overlying shales, on the other hand, show the transition to more oxic conditions. The redox conditions interpreted above are in agreement with the independent biomarker analyses and paleontological observations.

Opis:
We report cyrtocrinid (Crinoidea) ossicles from the Rhaetian (Late Triassic) of the Tatra Mountains (southern Poland). The columnals are high, the facets are covered with thick crenulae and the latera are concave. Such features of symplectial articulation and latera distinguish them from the columnals of other Triassic crinoids (i.e., millericrinids and encrinids) and therefore we consider they belong to Cyrtocrinida. The oldest representatives of cyrtocrinids were known from the Early Jurassic, therefore the presented material constitutes the oldest world record of these crinoids to date. We speculate that perturbations related to the global mid−Carnian extinction combined with predation intensity observed in the Middle– Late Triassic have been involved in early origin of Cyrtocrinida.

Opis:
Distinct faunal accumulations in the uppermost Bajocian/lowermost Bathonian, lowermost and Middle Bathonian of the Polish Jura (south-central Poland) have been detected. The fossils are densely packed in the centre of the accumulations and more or less dispersed in their margins. The accumulations vary in size, but all are rich in various groups of organisms, of which the molluscs (mainly bivalves) and echinoderms predominate. The echinoderms are all disarticulated, and shelly fauna occur as angular fragments with sharp edges, of random sizes and without any signs of abrasion. The different sizes of the fossil remains, from tiny echinoderm ossicles or juvenile shelly fauna to medium-sized shell fragments or belemnite rostra, exclude any transportation and thus sorting. Worth of noting is the occurrence of similar faunal groups in each accumulation. The general shape and composition of the accumulations, as well as their taphonomical features, especially the angularity of shell fragments, point to durophagous (shell-crushing) predation rather than physical processes. The various organisms may indicate that the potential predator (most probably fish) fed on various invertebrates. The indigestible particles were later regurgitated forming the accumulations discussed. The presence of various epibionts on the fossil fragments indicate,that they rested upon the sea-floor for some time-span after they had been regurgitated. Then the scavengers, as well as current action or water movements, have been responsible for dispersion of some of the fossils, as is well-visible at the margins of the investigated accumulations..
