The fossil's characteristics include a robust build with a prominent sagittal crest. Its distinct coloration is due to the high manganese content of the material it was embedded in. [2] This fossilized cranium's face projects far outward from the forehead, has wide flared zygomatic arches, and has a large sagittal crest. The molar and premolar ...
A sagittal crest is a ridge of bone running lengthwise along the midline of the top of the skull (at the sagittal suture) of many mammalian and reptilian skulls, among others. The presence of this ridge of bone indicates that there are exceptionally strong jaw muscles. The sagittal crest serves primarily for attachment of the temporalis muscle ...
Roughness appears in the sagittal crest and its located further back by the nuchal crest of gorillas and apes. The KNM-ER 406 sagittal crest is situated near the frontal bone and the highest point of the sagittal crest is located more medially. The development of the robusticity comes from the anterior part of the temporals muscles.

The first species found by the Leakeys, Zinjanthropus boisei or Australopithecus boisei (renamed and still debated as Paranthropus boisei), featured a sagittal crest and large molars. These attributes suggested the species engaged in heavy chewing, indicating a diet of tough plant material, including tubers , nuts , and seeds —and possibly ...
Scientists have found the U.K.’s largest dinosaur footprint site ever.. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...
The largest skulls of Paraceratherium are around 1.3 metres (4.3 ft) long, 33 to 38 centimetres (13 to 15 in) at the back of the skull, and 61 centimetres (24 in) wide across by the zygomatic arches. Paraceratherium had a long forehead, which was smooth and lacked the roughened area that serves as attachment point for the horns of other ...
The snout was strongly compressed laterally, and the premaxillae gently tapered towards the top to form a tall sagittal crest 1 to 2 mm (0.039 to 0.079 in) in thickness. This crest was larger and extended farther forwards on the snout than in other known spinosaurids.
