Jebel Boulouha tracksite (Cretaceous of Tunisia)

Where: Tataouine, Tunisia (32.9° N, 10.3° E: paleocoordinates 16.0° N, 8.8° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Neolobites medeninensis ammonoid zone, Kerker Member (Zebbag Formation), Late/Upper Cenomanian (99.6 - 93.5 Ma)

• 15 m below the top of the Kerker Member, several layers with tracks

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; fine-grained, dolomitic, yellow sandstone and limestone

• Arid tidal flat environment
• Mammal tracks in a "light to yellowish, fine-grained and biolaminated sandstone, showing early dolomitization and birds eye structures in thin section." Bird tracks in "a laterally persistent layer of finely laminated limestone"

Size class: macrofossils

Preservation: trace

Collected in 2004, 2010–2011

• Field data presented in this study were collected between February 2010 and March 2011. A mold of the two trackswasmade using SILICAL 110 silicone rubber. A fiberglass cast of the mold was also produced and deposited at the Museo Geologico Giovanni Capellini in Bologna (Italy) (accession number MGGC 21855).
