Dinosaurs That Start With B
Discover a complete list of over 65 dinosaurs that start with the letter B.
Each dinosaur listed has a dedicated page with information on classification, diet, size, fossil evidence, geographic distribution, and maps of known fossil locations, where available. Pages may also include size comparison charts, fossil representations, and in-depth descriptions based on current scientific research.
The amount of information varies by species, depending on the completeness of fossil discoveries.
Diet: Uncertain.Size: UnknownTime Period: Cenomanian/Turonian of the Cretaceous.
Diet: Carnivore.Size: Unavailable.Time Period: Early Cretaceous.
Diet: Herbivore.Size: 2.2†‬meters long.Time Period: Aptian of the Cretaceous.
Diet: Uncertain,†‬but possibly an omnivore as has
been presumed for other ornithomimosaurs.Size: Estimated at up to†‬8†‬meters long.â€
‬Analysis of remains suggests that they were of a subadult and the
dinosaur grew slightly larger.Time Period: Aptian/Albian of the Cretaceous.
Diet: Herbivore.Size: Around†‬4.8†‬to†‬5†‬meters long for the
remains found, though older individuals would have likely been larger.Time Period: Callovian of the Jurassic.
Diet: Carnivore.Size: Unavailable.Time Period: Pleinsbachian/Toarcian of the Jurassic.
Diet: Omnivore�‬/Herbivore�Size: Uncertain due to holotype being described from
an immature individual,†‬but possibly under a meter long.Time Period: Unknown due to†‬uncertainty of the
date of the Fossil Formation at the time of description,†‬but
probably†‬somewhere between the Aptian to†‬the Campanian of the
Cretaceous.
Diet: Carnivore.Size: Uncertain due to incomplete remains.Time Period: Maastrichtian of the Cretaceous.
Diet: Carnivore.Size: Estimated around†‬2.5†‬to†‬3†‬meters long.Time Period: Turonian of the Cretaceous.
Diet: Herbivore.Size: Unknown due to lack of fossil remains.Time Period: Early Jurassic.
Diet: Herbivore.Size: Unavailable.Time Period: Berriasian of the Cretaceous.
Diet: Herbivore.Size: Unknown due to lack of remains.Time Period: Turonian of the Cretaceous.
Diet: Carnivore.Size: Estimated†‬9†‬meters long.Time Period: Campanian of the Cretaceous.
Diet: Herbivore.Size: Preserved length of skull is about one and a
half meters,†‬but this is missing most of the neck frill.†‬Total size
uncertain.Time Period: Campanian of the Cretaceous.
Diet: Herbivore.Size: Uncertain due to lack of fossil remains.Time Period: Maastrichtian of the Cretaceous.
Diet: Herbivore.Size: Uncertain due to lack of adult remains,†‬but
thought to be no more than a few meters in length.Time Period: Aptian of the Cretaceous.
Diet: Presumed insectivore.Size: Estimated at†‬2.6†‬meters long.Time Period: Late Campanian/Early Maastrichtian of
the Cretaceous.
Diet: Herbivore.Size: Roughly estimated at about†‬7†‬meters long.Time Period: Campanian/Maastrichtian of the
Cretaceous.
Diet: Herbivore.Size: Uncertain due to lack of remains,†‬but is
noted as being of a small size.Time Period: Campanian-Maastrichtian of the
Cretaceous.
Diet: Herbivore.Size: About†‬9†‬meters long,†‬possibly larger
when fully grown.Time Period: Santonian of the Cretaceous.
Diet: Herbivore.Size: Holotype individual estimated to be aboutâ€
‬5.5†‬meters long.Time Period: Albian of the Cretaceous.
Diet: Herbivore.Size: Estimated about†‬12†‬meters long.Time Period: Late Albian/early Cenomanian of the
Cretaceous.
Diet: Carnivore.Size: Uncertain due to lack of fossil remains.Time Period: Campanian of the Cretaceous.
Diet: Carnivore.Size: Uncertain due to lack of remains,†‬but
roughly estimated to be about†‬2†‬meters long.Time Period: Campanian/Maastrichtian of the
Cretaceous.
Diet: Herbivore.Size: Uncertain due to lack of remains.Time Period: Kimmeridgian of the Jurassic.
