Additional Dinosaur Wildshapes

I have been looking to create a Druid that only wildshapes into dinosaurs and prehistoric beasts. This however only gives you four options at level four.

I have 'adapted' some other beast shapes to be dinosaurs.

Pachycephalosaurus = Giant Goat

Compsognsus = Weasel

Ichthyosaurus = Reef Shark

Dyoplosaurus (a smaller anklosaurus) = Boar (but slashing is replaced with bludgeoning)

Therizinosaurus = Giant Hyena (But bite is now a slashing claw attack)

Terror Bird = Axe Beak

Does anyone have any other suggestions?

Check this out.  Beasts of the jungle rot is great too and is even adventurers league legal.

I made an Argentinosaurus by using the Brontosaurus that's already a thing and did the following:

Since its Colossal in scale I used the Stat-block of the Bronto Replaced Hit-dice with a colossal Red Dragon

Replaced any Tail attacks with Stomps & Neck swings & boosted damage dice up by 1 size and added 2 more dice to that.

Made a Custom Rearing Stomp (See Jurassic Park Brachiosaurus rearing up to see this attack) its a 12d12+STR + CON Mods (Because your attacking not just with your strength but also you just standing on the target)

My DM both Loved and HATED this because for one my Druid was a Goblin and 2 we both agreed it made sense.
