Tendaguru quarry Ig, Kindope (Jurassic of Tanzania)

Also known as Quarry Jg, Dysalotosaurus Quarry, quarry WJ, British Expedition

Where: Lindi, Tanzania (9.7° S, 39.2° E: paleocoordinates 29.4° S, 16.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Middle Dinosaur Member (Tendaguru Formation), Late/Upper Kimmeridgian (155.7 - 150.8 Ma)

• formerly Middle Saurian Bed

•Scwarz et al. 2023: at least three levels within the member contain Dysalotosaurus bonebeds at this site.

•Heinrich (2001): Miospore and dinoflagellate assemblages recovered from matrix, housed in the Museum fur Naturkunde Berlin (Institut fur Palaontologie), suggest a Kimmeridgian to Tithonian age for bone bed Wj (Schrank 1999, 2000), whereas associated charophytes (Schudack 1999) and ostracods (Schudack & Schudack 2001) indicate a Kimmeridgian age for this bone-bearing deposit. Further biostratigraphic studies are needed to determine more precisely the age of the two bone beds at Tendaguru Site dy.

• group of beds-level stratigraphic resolution

Environment/lithology: channel lag; intraclastic, gray, green, red, sandy siltstone

• tidal channel deposit
• "greenish-grey and reddish sandy marls"; "intraclast-bearing sandy siltstone"

Size classes: macrofossils, mesofossils

Collected by W. Janensch, H. Reck, Parkinson in 1910–1913, 1927

Collection methods: quarrying, mechanical, acetic,

• Heinrich (1999) dissolved about 500 kg of matrix ('bone bed Wj') housed in the collections of the Museum of Natural History of Humboldt-University, Berlin in acetic acid resulting in discoveries of isolated tetrapod teeth
