Millions of years ago, gigantic dinosaurs dominated the earth's ecosystems. All that remains of the extinct giants are bone remains, which still give rise to many questions today. With his dynamic drawings, British palaeontologist Dr Mark Witton shows us the habitats and the respective shapes of the dinosaurs according to the latest research and takes us on a fantastic journey into prehistoric times. With scientifically based information texts on the individual species. Like all Ackermann calendars, produced exclusively in Germany and printed climate-neutrally in co-operation with NatureOffice on paper sourced from well-managed, FSC®-certified forests and other controlled sources.
