Some of the armored sauropoda are in my list for creatures I need specifically for my campaign setting. Cleon, you did at one time ask me if there was a list I did not post here...
Here for dinos and
here for prims. Both of those and more content is featured on the
Elftown wikipage for Nym (setting).
Okay, I'll have a look at your dinosaur list...
...Hmm, the
Megaraptor stats I posted back on page 1 of this thread will do for
Baryonyx in a pinch, and I think I've pretty well covered most of the Sauropods and Thyreophoran armoured dinosaurs.
I've already got takes on
Coelophysis,
Dilophosaurus, Spinosaurus and Ornithomimosaurs practically finished, so I can hopefully post those in a day or three.
EDIT: Hold on, I'd already posted my
Ornithomimid stats when I unveiled my take on
Deinocheirus.:EDIT
That would seem to leave Scythe-Lizard (e.g. Segnosaurus), Horn-Face (Ceratopsians & Protoceratopsians) and Bird-Foot (Iguanodons & Hadrosaurs) dinosaurs as the main standouts on your "want lists". I started roughing out some Therizinosaurs a few weeks ago but got distracted by work, so those would (most likely) be the first type I'd do, followed by the Horned Dinosaurs, although I'll release the lighweight theropods I mentioned in the previous paragraph first.
It would also be pretty easy to scale down my
Deinonychus and
Utahraptor stats to create the smaller Dromaeosaurs such as
Velociraptor (Small),
Bambiraptor (Tiny), but I think I'd want to do a more elaborate write-up like I did for the Sauropods and Thyreophorans so I can include the various other Maniraptors: the Diminutive
Epidexipteryx; the more lightly armed
Troodontidae; the winged and half-winged (
Sinornithosaurus, Rahonavis, Archaeopterytx et cetera) and the short-armed
Unenlagiinae.
As far as my stats are concerned whiptails are a standard feature of most of the sauropods.
I thought about including spine-backed sauropods but most sauropod spines were fairly small they'd probably not do much as far as the animal's D&D stat go, so I decided to consider them to be for display or species recognition of a a standard generic Sauropod, or just part of the armour of an Armoured sauropod to cover the most exaggeratedly spiny genera like Augustina.
I agree with that choice - if they are not big enough to make a difference in attack, and don't add to AC it's not worth adding - but natural AC is a good idea.
Ugh! I must have written that in a hurry, judging by the typos. I'll have to edit it for grammar, so I do not have to face the shame of it.
I was also thinking about reach and our long-necked friends... And even though MMI outlines certain guidelines for creating a standard creature of a standard shape and size, these critters (esp. dinos) are in many ways completely unique to D&D stats for other creatures like ogres and tarrasques - for the simple fact that they have very unique and extended physiology that I think begs for changed stats with certain attacks (such as bite or tailwhip attacks for sauropoda, for example - because of incredibly long necks and tails exceeding typical stats for a creature of that build. In other words, I think some things could be tweaked because of specific physiology which warrants it.
Yes, I think having a maximum reach of triple space is a reasonable upper limit. If I remember correctly, there are 3E stats for an awl pike which give it triple reach, and I think of a Diplodocus's tail as having a similar extravagant extent.
Minmi makes me smile to think about it.... I would adore having a little ankylosaur of that size of smaller. I bet they would be like a cow..... but I want one to play fetch with....
I'd think a
Bambiraptor would make a cuter pet, and be more likely to enjoy fetch.
