  2. Jugal bone - Wikipedia

    en.wikipedia.org/wiki/Jugal_bone

    The jugal bone is located on either side of the skull in the circumorbital region. It is the origin of several masticatory muscles in the skull. [1] The jugal and lacrimal bones are the only two remaining from the ancestral circumorbital series: the prefrontal, postfrontal, postorbital, jugal, and lacrimal bones. [2]

  3. Siamraptor - Wikipedia

    en.wikipedia.org/wiki/Siamraptor

    The finds included bones from a theropod new to science. [1] In 2019, the type species Siamraptor suwati was named and described by Duangsuda Chokchaloemwon, Soki Hattori, Elena Cuesta, Pratueng Jintasakul, Masateru Shibata and Yoichi Azuma. The generic name is derived from "Siam", the former name of Thailand, and the Latin word raptor ("robber").

  4. Protoceratops - Wikipedia

    en.wikipedia.org/wiki/Protoceratops

    The squamosal touched the jugal (cheekbone) and was very enlarged and high having a curved end that built the borders of the frill. The parietals were the posteriormost bones of the skull and major elements of the frill. In a top view they had a triangular shape and were joined by the frontals (bones of the skull roof).

  5. Asiatosuchus - Wikipedia

    en.wikipedia.org/wiki/Asiatosuchus

    depressifrons can be distinguished from all other species of Asiatosuchus by a combination of several characteristics including a large hole and a depressed area on the jugal bone of the skull, a frontal bone that does not touch the supratemporal fenestrae (two holes at the top of the skull behind the eye sockets), and a postorbital bone behind ...

    The epijugal is a dermal ossification unique to ceratopsians. It caps the bottom end of the downward-facing, triangular flange of the jugal that is typical for the group. In Arrhinoceratops and Pentaceratops, the epijugal forms a distinct jugal horn. The bone can be found in Yamaceratops and all ceratopsians more derived than the latter.

  7. Geography of Asia - Wikipedia

    en.wikipedia.org/wiki/Geography_of_Asia

    These varying definitions are not generally reflected in the map of Asia as a whole; for example, Egypt is typically included in the Middle East, but not in Asia, even though the bulk of the Middle East is in Asia. The demarcation between Asia and Africa is the Suez Canal, the Gulf of Suez, the Red Sea, and the Bab-el-Mandeb.

  8. Crichtonpelta - Wikipedia

    en.wikipedia.org/wiki/Crichtonpelta

    One of these was an autapomorphy, unique derived trait: the apex of the (quadrato)jugal, or cheek, horn, is pointing upwards. Also a unique combination of in themselves not unique traits is present. The upper snout armour forms an amorphous mass, not clearly separated into distinctive tiles. The jugal bone is deeper than that of Pinacosaurus.

  9. Quadratojugal bone - Wikipedia

    en.wikipedia.org/wiki/Quadratojugal_bone

    In tetrapods with a quadratojugal bone, it often forms a portion of the jaw joint. Developmentally, the quadratojugal bone is a dermal bone in the temporal series, forming the original braincase. The squamosal and quadratojugal bones together form the cheek region [4] and may provide muscular attachments for facial muscles. [5]
