Dinosaur, Anatotitan, (Trachodon)

Dinosaur, Anatotitan, (Trachodon)
By Audrey.m.horn – Own work, CC BY-SA 4.0,

This massive creature has a leathery hide, long slender limbs and a wide beak somewhat like that of a duck.

Anatotitans are huge herbivorous ornithischians that are generally harmless unless provoked.

The average anatotitan is 30 to 40 feet long and can weigh up to 3-4 tons. Despite its bulk, it is shy and not aggressive. Anatotitans, like other hadrosaurs, rear their young and have large herds consisting of one or more families. They are quite resistant to cold temperatures, despite their reptilian appearance.

This dinosaur is also known as Anatosaurus, and by the archaic name of Trachodon.

  • Trampling Charge. If the Hadrosaur moves at least 20 feet straight toward a creature and hits that creature with a Ram attack on the same turn, that target must succeed on a DC 13 Strength check or be knocked prone. If the target is knocked prone, the Hadrosaur may make one Stomp attack against it as a bonus action.


  • RamMelee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 9 (1d10 + 4) bludgeoning damage.
  • StompMelee Weapon Attack: +6 to hit, reach 5 ft., one prone creature. Hit: 17 (3d8 + 4) bludgeoning damage.


A generally placid and peaceful grazer of grass and ferns, the Hadrosaur is a danger only in large numbers. Shy, these creatures prefer to avoid trouble. However, each herd keeps several of its number on lookout. When danger threatens, the herd bunches together, placing young and pregnant females in the center. If the threat attacks, the herd attempts to move away en masse, but this direction is always away from the first threat and might lead to them trampling other hunters or running into a more dangerous situation.

Anatotitans avoid combat whenever possible, preferring to flee from confrontation. If their young are threatened, however, they fight with their powerful tails. 

An anatotitan will only make a trample attack as part of an escape attempt, or if pursuers are too vigilant.

Trample (Ex): An anatotitan can literally run over any creatures in its way that are of Large or smaller size. Creatures trampled must make a Reflex save (DC 24 half) or take 2d10+12 damage. The save DC is Strength-based.

Originally found in the first edition Monster Manual (1977, Gary Gygax), Monstrous Compendium MC3 – Forgotten Realms Appendix I (1989), and Monstrous Compendium Annual Two (1995). It also appeared in the original D&D module X1 – The Isle of Dread (1981, David Cook and Tom Moldvay).
