Where: Santa Cruz, Argentina (49.5° S, 71.5° W: paleocoordinates 56.5° S, 48.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Mata Amarilla Formation, Middle Cenomanian (99.6 - 93.5 Ma)

• Recently, precise U-Pb dating using laser ablation in zircons from continental facies from the middle section of the formation, gave 96.23 +/- 0.71 Ma in a tuff horizon about 28 meters above of the corresponding horizon where the insect and interactions were found. The fossiliferous level is situated stratigraphically above the MAL and MEL plantiferous levels from Iglesias et al. (2007).

• bed-level stratigraphic resolution

Environment/lithology: lacustrine; lithified shale

Size class: macrofossils

Preservation: adpression

Collection methods: Repository: Museo Provincial Padre Manuel Jesús Molina, Río Gallegos, Santa Cruz Province, Argentina (MPM)
