 Immediately beside this ridge is a shallow depression that becomes wider near the top of the tooth, which is probably the same structure as the groove interpreted by some authors.Theriodonts usually replace their teeth in an alternating (or distichial) pattern, such that the canine tooth is always functional; both skulls of "Euchambersia" show no sign of any replacement teeth developing, suggesting that "Euchambersia" was reliant on having both canines present and functional simultaneously.Behind the incisors and canines, there were no additional teeth in the jaw.
