Chitinozoan implications in the palaeogeography of the East Moesia, Romania

Palaeomagnetic data from Moesia are absent and previous palynological and macrofaunal studies could not show clearly the palaeogeographical position of Moesia between the larger palaeocontinents Gondwana, Baltica, or Avalonia. Cutting samples from three boreholes on East Moesia (SE Romania) have been investigated in this study using S.E.M technique. Chitinozoan assemblages prove the presence of Wenlock–Ludlow (possibly Homerian and Gorstian), Přídolí, and Lochkovian. Those of the last have a pronounced distribution in North Gondwanan localities; one of them, Cingulochitina plusquelleci, is illustrative only in North Gondwanan regions. These chitinozoans argue that East Moesia and probably West Moesia were in good communication with the Ibarmaghian Domain of the Northern Gondwana palaeocontinent.
