Carnotaurus is further characterized by small, vestigial forelimbs and long and slender hindlimbs. Its tail is extremely wide.

Compsognathus
Compsognathus is a small, bipedal animal with long hind legs and longer tails, which it uses for balance during locomotion. The forelimbs are smaller than the hindlimbs and featured three digits equipped with solid claws are suited for grasping prey. Its delicate skull is narrow and long, with tapered snouts.
It usually measures 3 feet in length and weighs around 5 pounds. Due to its small size, it hunts and scavenges in packs.

Dilophosaurus
These dinosaurs are 22 feet long, weighs around 1,600 pounds, and stands on two legs. The most distinctive characteristic of Dilophosaurus is the pair of rounded crests on its skull, which are used for display. It tends to stay near water, as its diet consists of fish.
Variant: Spraying Dilophosaurus
As seen on Jurassic Parc, where the author added it in, dilophosaurus can spray poison in front of itself, blinding prey in the process. A spraying dilophosaurus has a challenge rating of 2 (450 XP) and the following action option.
Spray Poison (Recharge 6). The dilophosaurus sprays poison in a 15-foot cone. Each creature in that area must make a DC 13 Constitution saving throw. On a failure, the creature takes 20 (8d4) poison damage and is blinded for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
If the saving throw is successful, the target takes half the poison damage and isn't blinded.

Tail. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 14 (2d8 + 4) bludgeoning damage.
Its head is larger than a person, with high eyes and a crest on its nose, similar to that of a rooster's. It rests on a neck that has the posture of a pelican. Its most significant, distinctive feature is a huge 8-foot-high sail in the shape of an M on its back.
It is semi-aquatic, as such tends to stay near water. On the ground, it is rather slow and therefore will not pursue prey too far inland.
Even a teenager spinosaurus is the size of a
tyrannosaurus, and the mother is the one that teaches
them to hunt, while also being very
protective of them.
Dinosaurs
These are additional encounters meant to be used with the Wilderness Encounters table in Tomb of Annihilation. The table below replaces the Dinosaur section of the Wilderness Encounters table in Tomb of Annihilation.
Carnotaurus. The party has a 150-foot, 40-foot high, 30-foot wide escarpment leading to the jungle or to the beach (depending on where the party is). If a character gets about half-way through it, a carnotaurus steps out on the other side of the canyon and attacks. A character that decides to climb up or down the canyon must succeed on a DC 15 Strength (Athletics) check or fall a number of feet equal to 1d4 times 10. From the top of the cliff, a character can notice the carnotaurus waiting for prey to enter the canyon.
Compsognathus. A pack of 1d6 + 1 swarms of compsognathuses and a 1 compsognathus spot the characters.
If this encounter occurs during the day, the lone dinosaur reveals itself to the party, while the others surround the party. Make a single Dexterity (Stealth) check for the swarms, with advantage. If any character is aware that these are pack carnivores, and that character's passive Wisdom (Perception) score exceeds the swarms', it is not surprised if they attack. The compsognathuses can be distracted by tossing 5 or more days supply of food. Otherwise, they attack.
If this encounter occurs at night, the compsognatuses enter their camp, looking to steal food. Any character on guard spots them with a successful DC 17 Wisdom (Perception) check. If a character means to attack or otherwise hit any of them, they run away. Otherwise, they steal 3d4 days of rations and leave.
Dilophosaurus. The characters stumble upon 1d4 dilophosauruses fishing in a small stream. The dinosaurs feel threatened and show signs of defending their source of food. If the characters immediately back away slowly, the dinosaurs go back to fishing. Otherwise, they attack.
Pachycephalosaurus. In a small clearing are 2 male, 1d4 female pachycephalosuaruses, with 1d4 noncombatants among them. The males are fighting, while the females watch for who will prevail. If the characters make themselves known, the females cry out, stopping the fight between the males. If the characters get within 30 feet of any of them, they attack. The young are Small beasts that can be sold to Ifan Talro'a in Port Nyanzaru for 50 gp each, or for 100 gp if a character succeeds on a DC 15 Charisma (Persuasion) check to negotiate the price. The young dinosaurs are easy to handle if separated from their parents, but the adults fight if their young are captured.
Spinosaurus. A spinosaurus and 1d2 young spinosauruses prowl a nearby river, near a bank. If a character goes to collect water, is on the river, or the party crosses the river, the adult will attack. Any character near the water with a passive Wisdom (Perception) score of 15 or higher spot the young before they attack; all other characters are surprised. The mother joins the fight if any one of the young is reduced to half health, otherwise she stays hidden. If the characters get more than 100 feet away from the water, the spinosauruses do not follow.
