Dinosaurs That Start With D
Discover a complete list of over 54 dinosaurs that start with the letter D.
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: Carnivore.Size: Typically about 6 meters long, some fossils
suggest larger individuals may have attained lengths of up to 7 meters..Time Period: Sinemurian of the Jurassic.
Diet: Herbivore.Size: Uncertain,†‬but roughly estimated at†‬2.3â€
‬meters long for adults.Time Period: Albian of the Cretaceous.
Diet: Carnivore.Size: Estimated about†‬2.5†‬to†‬3†‬meters long.Time Period: Maastrichtian of the Cretaceous.
Diet: Herbivore.Size: Uncertain, but roughly estimated to be about
25 meters long.Time Period: Kimmeridgian of the Jurassic.
Diet: Herbivore.Size: D. carnegii about 24 meters long. D. hallorumabout 3-33 meters long.Time Period: Kimmeridgian to Tithonian of the Jurassic.
Diet: Herbivore.Size: Unavailable.Time Period: Barremian/Aptian of the early
Cretaceous.
Diet: Herbivore.Size: Unavailable.Time Period: Albian/Cenomanian of the Cretaceous.
Diet: Herbivore.Size: Uncertain but estimated to be somewhere aboutâ€
‬15†‬meters long.Time Period: Estimated at some point during the
earlier stages of the Late Cretaceous.
Diet: Herbivore.Size: Roughly estimated to have been†‬3.5†‬meters
in length.Time Period: Tithonian of the Jurassic.
Diet: Herbivore.Size: Uncertain due to lack of remains,†‬but
possibly somewhere around the two meters long mark.Time Period: Late Tithonian of the Jurassic.
Diet: Carnivore.Size: Holotype estimated to have been†‬2.1†‬meters
long,†‬however this was a juvenile at the†‬time of death.†‬Adults
may have been up†‬3†‬meters long.Time Period: Hettangian of the Jurassic.
Diet: Herbivore.Size: Uncertain due†‬to lack of remains,†‬but the
holotype is roughly established as having a body length of about†‬3â€
‬meters long.Time Period: Maastrichtian of the Cretaceous.
Diet: Carnivore.Size: Uncertain due to lack of more complete
remains,†‬but roughly estimated about†‬5.5†‬to†‬6.5†‬meters long.Time Period: Hettangian-Sinemurian of the Jurassic.
Diet: Herbivore.Size: Up to†‬26†‬meters long and around†‬59â€
‬tons in weight for the holotype individual,†‬fully grown adults would
have been larger,†‬but total size cannot yet be confirmed.Time Period: Campanian/Maastrichtian of the
Cretaceous.
Diet: Herbivore.Size: About†‬2†‬meters long.Time Period: Late Jurassic.
Diet: Carnivore.Size: Comparison to dromaeosaurid theropod dinosaurs
indicates that this dinosaur may have reached lengths of about 3 to 4
meters long.Time Period: Berriasian of the Cretaceous.
Diet: Carnivore.Size: Up to 2 meters long.Time Period: Campanian of the Cretaceous.
Diet: Herbivore.Size: Unavailable.Time Period: Cenomanian to Turonian of the
Cretaceous.
Diet: Herbivore.Size: 2.4 - 4.3 meters long, though possibly more
for large adults.Time Period: Late Jurassic.
Diet: Carnivore.Size: Around†‬7.5†‬meters long.Time Period: Maastrichtian of the Cretaceous.
Diet: Carnivore/Piscivore.Size: 9†‬meters long.Time Period: Bathonian of the Jurassic.
Diet: Herbivore.Size: Uncertain due to lack or fossil remains.Time Period: Kimmeridgian of the Jurassic.
Diet: Carnivore.Size: Skull estimated to be about 60 centimetres
long.Time Period: Bajocian of the Jurassic.
Diet: Carnivore.Size: Roughly estimated at†‬9†‬meters long.Time Period: Campanian of the Cretaceous.
Diet: Herbivore.Size: Uncertain due to lack of complete remains,â€
‬but estimated between†‬4†‬and†‬4.5†‬meters long.Time Period: Campanian of the Cretaceous.
