Geography
| Country: | Argentina | State/province: | Santa Cruz |
| Coordinates: | 49.5° South, 71.5° West (view map) | ||
| Paleocoordinates: | 48.4° South, 36.3° West (Wright 2013) | ||
| Basis of coordinate: | stated in text | ||
| Geographic resolution: | outcrop |
Time
| Period: | Cretaceous | Epoch: | Late Cretaceous |
| Stage: | Cenomanian | 10 m.y. bin: | Cretaceous 5 |
| Key time interval: | Middle Cenomanian | ||
| Age range of interval: | 100.5 - 93.9 m.y. ago |
Stratigraphy
| Formation: | Mata Amarilla | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: 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). | |||||
