Ksar Mrabtine (Jurassic of Tunisia)

Also known as Ksar M'Rabtine

Where: Tataouine, Tunisia (33.0° N, 10.4° E: paleocoordinates 21.5° N, 11.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Khechem el Miit Member (Foum Tataouine Formation), Late/Upper Callovian (164.7 - 161.2 Ma)

• Dridi and Johnson, 2019: The Khechem El Miit Member was attributed to the middle-late Callovian based on the presence of the ammonoids Erymnoceras sp. and Pachyerymnoceras cf. philby and the brachiopods Daghanirhynchia daganiensis and Bihenithyris barringtoni (Peybernes et al., 1985; Ouaja, 2003).

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithology not reported

• Dridi and Johnson, 2019: This bed is interpreted as an exposed tidal plain
• Dridi and Johnson 2019: The fossils were found embedded in a thin bed of fine sand, which occurs sporadically with a limited lateral extent (Fig. 1(B)).

Size class: macrofossils

Collected by Le Loeuff et al. in 2000

Collection methods: surface (in situ), chemical,

• Dridi and Johnson, 2019: The fossils were removed from the surrounding matrix using traditional methods, restored by applying a polyvinyl acetate soluble in acetone (Vinac). They are currently housed in the geological/paleontological collection of the Muse ́e de la Géologie under the accession numbers ONM-KMR 1 (incomplete mandibular symphysis), ONM-KMR 2-4 (teeth), ONM- KMR 5-7 (vertebrae), ONM-KMR 8-16 (thoracic ribs), and ONM- KMR 17-29 (dorsal and ventral osteoderms).
