Where: Romania (45.1° N, 28.8° E: paleocoordinates 17.4° N, 33.3° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Aegean (247.2 - 242.0 Ma)
• The high-resolution ammonoid biostratigraphy in the Deşli Caira section, accurately
•demonstrates that the Spathian/Aegean boundary is placed a little higher in the section than had been previously estimated by Grădinaru et al. (2007). It is now placed between the levels 821 and 822A. The topmost part of the level 821 (821A) yields the uppermost Spathian ammonoid assemblage, including Procarnites kokeni (Arthaber, 1908), Eogymnites arthaberi (Diener, 1915), Proptychitoides sp., Albanites sp., and others, whilst the level 822A yields a lowermost Aegean ammonoid assemblage, including Aegeiceras ugra (Diener, 1895), Paracrochordiceras sp., Japonites sp., Stenopopanoceras sp., Lenotropites sp., and others.
