Most paleontological knowledge of this unit derives from the shale-dominated interval in its middle part, while fossil data from the sandstone-dominated facies in the uppermost part of the formation remain scarce. This paucity of data arises because the overlying deposits were either eroded or are currently obscured by Cenozoic gravity-flow deposits. Nonetheless, the uppermost Romualdo Formation preserves a tide-dominated delta succession, documenting the basin gradual return to continental conditions. In the Sobradinho section, a new mollusk-dominated assemblage is identified in an intraclast-supported conglomerate located ∼10 m above the upper shell bed interval. The assemblage includes bone fragments, plant remains, and marine/brackish-water mollusks. Additionally, freshwater bivalves, previously known only from the underlying Crato Formation, are also recorded. All macroinvertebrates exhibit a consistent preservational pattern, with infill composed of the rock matrix. Therefore, the freshwater bivalves are not reworked fossils from older sediments within the conglomerate. Their presence suggests that, for much of the Romualdo Formation depositional history, these freshwater bivalves thrived in riverine and/or low-salinity transitional or coastal environments. Without this new record, their known vertical distribution would remain largely confined to the bivalve-rich mudstones of the basal third of the Crato Formation and to a siltstone bed within a confined bay succession ∼100 m below the newly reported assemblage. This discovery significantly expands their stratigraphic range as facies-controlled Lazarus taxa.</div></div>","PeriodicalId":55207,"journal":{"name":"Cretaceous Research","volume":"175 ","pages":"Article 106165"},"PeriodicalIF":1.9,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained results show a major change in sedimentation in the middle Cenomanian when mixed carbonate and siliciclastic deposits were replaced by chalk. This transition reflects a major change in palaeoceanographic conditions toward a more stable circulation mode, with better connection between the different oceanic basins, persistent currents, and bottom ventilation. Cyclicity in the ln(K/Al) record indicates insolation-driven fluctuations in aridity and humidity. A new age model, based on the stable 405 kyr-long eccentricity cycles, places the onset of the OAE2 carbon isotope excursion at ∼94.74 Ma. Sedimentation during the OAE2 seemed to be mainly controlled by long-term processes and local effects rather than global perturbations.

The absence of metriacanthosaurids and basal tyrannosauroids in later formations suggests a faunal turnover, with allosaurians and spinosaurids becoming more prevalent, aligning with the changes in theropod faunal composition across Eurasia.
