摘　　要：Discovery of the remains of belemnites referred to the Hibolithes sp.from the Jurassic–Cretaceous Pedawan Formation in Sarawak,on the island of Borneo(Malaysia)comprises four fragments of belemnite rostra.The specimens are characterized by multiple fractures and vein filling.Two fragments measuring about 130 mm are relatively intact,with only part of the alveolar region missing;a third piece represents the middle part of a rostrum,and the fourth specimen is too fragmentary to be assigned to any specific part of the rostrum.Based on specimen characteristics,a Tithonian–Hauterivian age is plausible.The sedimentary succession that yielded the belemnite material comprises thick shale that reflects the Te division of Bouma sequence.The occurrence of a Hibolithes taxon in the uppermost Jurassic to lowermost Cretaceous Pedawan Formation sediments in Borneo reflects a near to global palaeobiogeographic distribution of this genus.
