On the question when mammals first started to rear their offspring, the jury is still out. Was such care-giving behavior actually inherited from our reptilian ancestors?

Cały czas trwa dyskusja, kiedy w ewolucji ssaków pojawiła się opieka nad potomstwem. Czy te zachowania zostały odziedziczone po gadzich przodkach?

Polscy naukowcy dokonali spektakularnego odkrycia. Na Śląsku znaleziono szczątki dużego drapieżnego dinozaura i najmłodszego z dotąd poznanych gada ssakokształtnego z grupy dicynodontów.

Paleontological research faces a persistent challenge: distinguishing genuine fossils from skillful forgeries – a task crucial for maintaining the scientific rigor and historical credibility of the discipline.

Fałszerstwa skamieniałości należą do podręcznikowych przykładów nadużyć w badaniach naukowych, wpływają negatywnie na ich jakość i wiarygodność szczególnie w paleontologii.

The Fleming Fjord Formation (Jameson Land, East Greenland) documents a diverse assemblage of terrestrial vertebrates of Late Triassic age. Expeditions from the turn of the 21st century have discovered many important fossils that form the basis of our current knowledge of Late Triassic Greenlandic faunas. However, due to the scarcity and incompleteness of the fossils and their insufficient study, our understanding of the taxonomic diversity of the Fleming Fjord Formation is hindered. Here, we report the preliminary findings of a Polish−Danish expedition to the Fleming Fjord Formation that took place in 2014. Three areas were visited – the fairly well known MacKnight Bjerg and Wood Bjerg and the virtually unexplored Liasryggen. MacKnigth Bjerg and Liasryggen yielded fossils which promise to significantly broaden our knowledge of vertebrate evolution in the Late Triassic. Stem−mammal remains were discovered at Liasryggen. Other fossils found at both sites include remains of actinopterygians, sarcopterygians, temnospondyl amphibians and various archosaurs (including early dinosaurs). Numerous vertebrate trace fossils, including coprolites, pseudosuchian footprints, theropod and sauropodomorph dinosaur tracks, were also discovered. Newly discovered skeletal remains as well as abundant trace fossils indicate higher tetrapod diversity in the Late Triassic of Greenland than previously thought. Trace fossils also allow inferences of early theropod and sauropodomorph dinosaur behaviour.
