Stratigraphy
| Formation: | Paja | ||||
| Stratigraphy comments: Belonging to the middle segment of the Paja Formation called “Arcillolitas abigarradas”, which is upper Barremian-lower Aptian in age (~120 Ma), based on the presence of the Pseudocrioceras ammonite assemblage zone. |
Lithology and environment
| Primary lithology: | ferruginous,nodular,gray lithified calcareous "limestone" |

All specimens are preserved in a predominantly dark grey limestone. They have a layer of ferruginous oxides that frequently covers the exterior surface of the bones and fills in cavities. | |
| Environment: | marine indet. |

| Modes of preservation: | body |
| Size of fossils: | macrofossils |
