Dunkleosteus terrelli fish jaw replica dimensions

  • Size: 16.7 inches (42.5 cm) in length.
  • Scale: Life-size representative of a mature adult specimen.

Product Details

  • Material: Museum-quality polyurethane resin cast of original specimen.
  • Anatomical Accuracy: Furthermore, it replicates the specialized shearing blades that functioned as self-sharpening teeth in this armored placoderm.
  • Origin: Made in USA.
  • Features: Specificaly, this cast captures the dense, bony texture of the plates found in the Cleveland Shale.

Scientific Information:

  • Bite Force: For example, it had a force of 6,000 to 7,400 newtons, making it capable of crushing armored prey.
  • Jaw Mechanics: Utilized a four-bar linkage system to open its mouth in 20 milliseconds, creating a vacuum to suck in prey.
  • Morphology: Lacked true teeth; used massive bony plates that sharpened as they rubbed together.

Scientific Classification:

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: †Placodermi
  • Order: †Arthrodira
  • Family: †Dunkleosteidae
  • Genus: †Dunkleosteus
  • Species: D. terrelli
  • Binomial Name: Dunkleosteus terrelli (Newberry, 1873)
  • Temporal Range: Late Devonian (Frasnian–Famennian), approximately 382–358 million years ago.
  • Conservation Status: Extinct.

Although this fish is famous for its powerful bite, it shares a similar role in the marine food web with the Spotted Eagle Ray shark, both acting as top-tier predators of hard-shelled invertebrates.

Compare the shearing bony plates of the ancient Dunkleosteus with the serrated, enamel-covered predatory teeth of the Megalodon black shark tooth replica.
