Spinosaurus 2014
CR 13 beast
Gargantuan beast, Unaligned
The spinosaurus can hold its breath for 1 hour.
The spinosaurus never willingly attacks a reptilian Humanoid, such as a lizardfolk or dragonborn, unless attacked first. If magically forced to attack such a creature, the spinosaurus has disadvantage on attack rolls against it. This trait doesn’t function if the spinosaurus’s rider or tamer directs it to attack.
The spinosaurus deals double damage to objects and structures.

The spinosaurus makes one Bite attack and two Claw attacks.
Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 33 (4d12 + 7) piercing damage. If the target is a Large or smaller creature, it is grappled (escape DC 18). Until this grapple ends, the target is restrained, and the spinosaurus can't Bite another target.

Each creature of the spinosaurus' choice that is within 120 feet of the spinosaurus and aware of it must succeed on a DC 18 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the spinosaurus's Frightful Presence for the next 24 hours.
