Stratigraphy and paleoenviroment
The Bombarral Formation outcrops around Pombal, Portugal. It is considered a laterally equivalent but distinct rock sequence to the more well known Lourinhã Formation. It is interpreted as being deposited during the Tithonian of the Late Jurassic period.[1] Its Lithology is primarily represented of massive fine-grained, micaceous sandstones that are mixed with red mudstones. It is interpreted as having been formed in a floodplain ecosystem.[1]

|---|---|---|---|
| Brachiosauridae indet.[2] | Indeterminate | Postcranial material | Stated to have come from a 25 m long animal.[3] From outside sources, the authors imply that the remains belong to Lusotitan.[4] |
| Diplodocidae indet. | Indeterminate | Multiple skeletal remains | Multiple remains from indeterminate diplodocines.[5] Whether or not they come from one taxon or multiple is uncertain. |
| Turiasauria indet | Indeterminate | Teeth[6] | Multiple teeth from indeterminate turiasaurs. |
Theropods
| Genus | Species | Material | Notes |
|---|---|---|---|
| Allosaurus | A. europaeus | Multiple skeletal remains [1] | Validity disputed,Some authors argue instead that they belong to A.fragilis. |
| Torvosaurus | T.cf.gurneyi | Teeth[7] | Teeth referred to Torvosaurus on the basis of cladisitics and multivariate analysis. |
| Tyrannosauroidea indet. | Indeterminate | Teeth[8] | Teeth referred to indeterminate Tyrannosauroids. |
