In Depth

       Even though the name Eocarcharia‭ ‬means‭ ‘‬dawn shark‭’‬,‭ ‬it was actually a theropod dinosaur.‭ ‬This name came about from the serrated slicing teeth that are thought to have sliced through flesh as easily as a shark.‭ ‬The dawn part is‭ ‬a reference to its early appearance to some other related genera.‭ ‬Although only known from incomplete remains Eocarcharia has been identified as being a member of the Carcharodontosauridae,‭ ‬a group of theropod dinosaurs established around the type genus of Carcharadontosaurus,‭ ‬another dinosaur named for its tooth resemblance to a sharks.‭

       Some of the most noteworthy features of Eocarcharia are the enlarged bone growths above the eyes.‭ ‬These features likely served a display purpose,‭ ‬and may have been coloured differently to the rest of the head.‭ ‬Due to the incomplete nature of the remains only a broad ranged size estimate for Eocarcharia exists.‭ ‬This is based upon comparison to its more complete relatives,‭ ‬although it‭’‬s not unreasonable that larger estimates approaching twelve meters in length may be accurate given that it is a relative of Giganotosaurus,‭ ‬one of the largest known theropod dinosaurs.
