Mastodonsaurus giganteus’ face says it all–which is why we’re featuring it for #WorldEmojiDay.😐

Mastodonsaurus is an extinct relative of frogs and salamanders, but it probably behaved more like a crocodile. The large, flat skull with tusk-like teeth, some of which protruded through the skull, seems to be adapted for seizing large prey. It lived during the Late Triassic about 215 million years ago. See this life-size model of Mastondonsaurus giganteus in the Museum’s Hall of Vertebrate Origins.
