Converting prehistoric animals

I don't think they contradict one another. Run doesn't appear to benefit a creature when it makes a charge, whereas sprint does.

6x sounds reasonable to me.

Anything else?

I think it's done. What's next? I'm starting to run out of premade conversions!
According to my notes, these are the still unconverted dinosaurs. (I suspect that one or two may already have been converted under other names.)

From Dragon #112:
  • Dinosaur, Carnosaur
  • Dinosaur, Ceratopsian
  • Dinosaur, Chelonian, Marine
  • Dinosaur, Coelurosaur
  • Dinosaur, Crocodilian
  • Dinosaur, Cyndont
  • Dinosaur, Dicynodont
  • Dinosaur, Labyrinthodont
  • Dinosaur, Ormthopod
  • Dinosaur, Ornithomimosaur
  • Dinosaur, Phytosaur
  • Dinosaur, Prosauropod
  • Dinosaur, Rhynchosaur
  • Dinosaur, Sauropod
From Monstrous Compendium Annual Volume Two:
  • Dinosaur, Dinichthys
  • Dinosaur, Euparkeria (underway)
From Monstrous Manual:
  • Dinosaur, Lambeosaurus
From Lands of Intrigue:
  • Pythosaurus
From Dragon #187:
  • Shonisaurus

Are those all covered by existing conversions then? i.e. Can I drop all fourteen from the "still to be converted" pile? ;)

This large reptilian quadruped has a stiff tail, a duck-like beak and a plow- shaped crest on the top of its head.

Lambeosaurs are a species of hardrosaur that lives in large herds.

A lambeosaur is a very large animal, smaller than its relative the anatotitan, but still averaging over 30 feet long. It still is a common prey item for many carnivorous dinosaurs, but lambeosaurs live in large herds to protect themselves from danger. Each herd has a distant relationship with other nearby herds, and their crests act as powerful amplifiers for their hooting cries. The distress calls of a lambeosaur can be heard from almost a mile away, and if a distress call is given, other herds in earshot flee as rapidly as possible.

Lambeosaurs shy away from combat unless they or their offspring are threatened. If so, they fight using their powerful tails.

Trample (Ex): A lambeosaurus can literally run over any creatures in its way that are of Large or smaller size. Creatures trampled must make a Reflex save (DC 21 half) or take 2d10+9 damage. The save DC is Strength based.

Swap Toughness for something better?

Wikipedia said:
Like other lambeosaurines such as Parasaurolophus and Corythosaurus, Lambeosaurus had a distinctive crest on the top of its head. Its nasal cavity ran back through this crest, making it mostly hollow. Many suggestions have been made for the function or functions of the crest, including housing salt glands, improving the sense of smell, use as a snorkel or air trap, acting as a resonating chamber for making sounds, or being a method for different species or different sexes of the same species to recognize each other.
Is any of that of use?

Wikipedia said:
The large size of hadrosaurid eye sockets and the presence of sclerotic rings in the eyes imply acute vision and diurnal habits, evidence that sight was important to these animals. The hadrosaurid sense of hearing also appears to be strong.
Racial bonus on Listen and Spot checks?

Sadly, I can't think of a better feat. Let's give them +4 on Listen and Spot.

Do you want to add Stampede? That seems somewhat appropriate.


Extradimensional Explorer
I'm ready, too!

Maybe one of our resident paleontologists can answer the other question...
