The Dinosaur Alphabet: I

So, I can't explain exactly why, but my scanner has finally started to work as before. That's incredible! :")
Tell me now which dinosaur genera would you like to see for letter 'J'! thanks in advance!

From top to bottom:
- Irritator challengeri (close-up)
- Iguanodon bernissartensis (close-up)
- Incisivosaurus gauthieri (close-up)
- Isisaurus colberti

The scale for Iguanodon is approximate, the others are millimetrically accurate.
I've chosen to depict the first three in foreground since we know only the skull (by the way, very quaint and beautiful) of Irritator and Incisivosaurus, while Iguanodon postcranial skeleton is very similar to that of the vast majority of ornithopods.
Isisaurus is instead a very atypical titanosaur because of numerous postcranial features.
