Grdoselo forest track (Eocene of Croatia)

Where: Croatia (45.3° N, 13.9° E: paleocoordinates 38.8° N, 12.0° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lutetian (47.8 - 41.3 Ma)

• The Middle to Late Lutetian age of the rocks outcropping in Grdoselo has been determined by Miksa et al. (2005: 101) on the basis of orthophragmid foraminifera. They determined assemblages that correspond to biozones SBZ 14/15 or P11-P12. The nannofossil assemblage is typical of the Middle Eocene and allows the assignment to the biozone NP15 (Nannotethrina fulgens) of the Middle Eocene.

Environment/lithology: lithified, sandy packstone

Size class: macrofossils
