Austroraptor

Pack Tactics. The austroraptor has advantage on an attack roll against a creature if at least one of the austroraptor’s allies is within 5 feet of the creature and the ally isn’t incapacitated.

Pounce. If the austroraptor moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is prone, the austroraptor can make one bite attack against it as a bonus action.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 11 (2d6 + 3) piercing damage.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) slashing damage.
