Banglaceratops dhakaensis is a dubious and controversial dinosaur taxon tentatively assigned to Ceratopsidae, based on fragmentary fossil remains discovered in Bangladesh. The taxon was announced on 29 January 2026 following the recovery of partial postcranial material from Late Cretaceous sediments within the Dhaka Basin. If the material represents a ceratopsid, Banglaceratops would be among the largest horned dinosaurs ever proposed, with mass estimates approaching 15 metric tons.

Due to the limited nature of the fossil material and the anomalously large size estimates, the validity of Banglaceratops has been questioned, with alternative interpretations suggesting the remains may belong to a titanosaurian sauropod.

Discovery

The fossils were recovered during a joint geological and paleontological survey conducted by researchers from the University of Dhaka and the Leiden Institute of Earth Sciences in January 2026. The discovery site lies along the eastern margin of the Dhaka Basin, within fluvial sandstone deposits tentatively dated to the Maastrichtian stage of the Late Cretaceous.

The find was announced during a regional vertebrate paleontology symposium later that month.[1][2]

Etymology

The genus name Banglaceratops combines Bangla, referencing Bangladesh, with the Greek ceratops meaning “horned face”. The species name dhakaensis refers to the proximity of the discovery site to the city of Dhaka.

Material

The holotype specimen (DU-PV-2026-01) consists of:

  • A partial right femur
  • Several indeterminate bone fragments

No cranial material, including horn cores or frill elements diagnostic of ceratopsids, has been recovered. The femur displays a moderately expanded distal end and muscle attachment scars that show partial resemblance to large ceratopsian hindlimb morphology, though these traits are not exclusive to Ceratopsidae.

Size estimates

Femoral circumference scaling suggests a total body length of approximately 11–12 metres and a mass estimate of up to 15 metric tons. These estimates would far exceed the size of all confirmed ceratopsids, which are generally estimated to weigh between 6 and 10 metric tons.

Several authors have cautioned that such estimates may be inflated if the specimen represents a sauropod rather than an ornithischian dinosaur.

Classification

Banglaceratops dhakaensis was tentatively assigned to Ceratopsidae based on femoral proportions and overall robustness. However, the absence of cranial material prevents confident diagnosis.

Subsequent commentary has noted morphological overlap between the preserved femur and those of large-bodied titanosaurian sauropods known from Asia, raising the possibility that the remains may represent a misidentified sauropod or a chimeric assemblage.

Pending the discovery of additional diagnostic material, Banglaceratops is generally regarded as a nomen dubium.

Paleobiogeographic implications

If confirmed as a ceratopsid, Banglaceratops would represent the first ceratopsian dinosaur reported from Bangladesh and would significantly extend the known geographic range of derived ceratopsids into South Asia. These implications remain speculative.
