Reptile
Placodus gigas
Placodus gigasPlacodus gigas was a robust marine reptile adapted for life in shallow coastal waters during the Middle Triassic period. Its barrel-shaped body and heavily thickened bones acted as natural ballast, allowing it to cruise along the seabed without expending excess energy. Forward-projecting incisors plucked hard-shelled invertebrates from the substrate, while expansive, pavement-like palate teeth crushed them with formidable biting force.
