Overview
- The fossil mass contains partial remains of two Bakiribu waridza individuals alongside four fish, all preserved as a regurgitalite.
- Phylogenetic and paleohistological analyses, including well-preserved dentine and pulp cavities, support assignment to the filter-feeding Ctenochasmatidae.
- The discovery marks the first recorded ctenochasmatid pterosaur in Brazil and in rocks of this age from tropical latitudes.
- The specimen was long held in the Museu Câmara Cascudo collection with no precise provenance or collection date before being reexamined.
- Researchers suggest a spinosaurid or an ornithocheiriform pterosaur likely produced the regurgitalite, but the predator’s identity remains unconfirmed.
