Titanoceratops ouranos

[Species: Titanoceratops ouranos

Classification: Reptile, dinosaur, ornithischian

Diet: Herbivore; browser; eats ferns, cycads, and conifers.

Age: 75 million years (Mesozoic era, Cretaceous period, Late Cretaceous epoch, Campanian stage)

Height: 2.5 meters (8.2 feet) tall at the back.

Length: 6.8 m (22.3 ft)

Weight: 6.55 tonnes (7.22 short tons)

Habitat: Coastal floodplain

Appearance:

• A long, rectangular, bony frill behind the skull. Skull is 2.65 m (8.7 ft) long.
• The scallops on the frill were very low; the central bar of the parietal was a thin, keeled plate.
• The brow horns were huge, strongly curved forward, and had massive bases filled with a huge sinus, or air space.
• A short nasal horn positioned forward, at the front of the nostrils.
• Tall maxilla.
• A beak.
• Four legs.
• Erect limb posture; stands beneath the body.
• Elbows are flexed to behind and slightly bowed out.
• Semi-pronated wrists.
• Short, rigid tail.

Notable Info:

• Likely ancestor of Triceratops and Torosaurus. Shares more traits with these two dinosaurs than it does with Pentaceratops.
• The ball-and-socket joint, located at the base of the skull, allowed the skull to rotate in any direction.
• Dental batteries in the back of the mouth formed from hundreds of teeth which were stacked in rows upon rows and formed a grinding surface to process plant foods. Grew new teeth on the inside, which migrated over time to replace the outer teeth. Teeth in the rapidly growing dental battery would wear completely down and be reabsorbed by the renewing structure around it.]

Appearance:

• A long, rectangular, bony frill behind the skull. Has large triangular osteoderms: up to twelve episquamosals at the squamosal and three epiparietals at the parietal bone. Skull is 2.16–2.3 m (7.1–7.5 ft) long.
• The brow horns are very long and curve strongly forward.
• The nose horn is small and points upward and backward.
• Tall and wide torso.
• A beak.

[A browser is an herbivore that mainly eats leaves and shoots.]

[Non-avian dinosaurs wouldn't roar; they'd grunt, hiss, bellow, and honk. Infrasound (sound below human audibility (20 Hertz)) would also be used. With infrasonic pressure being high, the vibrations can be felt across the body.]
