Named after the Indian Statistical Institute
Late Cretaceous, 70 million years ago

Isisaurus’s long forelimbs and (relatively) short neck gave it what has been described as a “hyena-like” appearance. It was originally dubbed Titanosaurus colberti, but that genus has since been declared a “wastebasket taxon.” In 2003, it was renamed in honor of the Indian Statistics Institute (ISI), but lately Isisaurus is maaaaybe considering another name change.

I is for Iguanodon and friends

A little “I” dinosaur menagerie today (plus an ichthyosaur):

Iguanodon bernissartensis - Thumb spikes! Also, no matter how many times I’ve seen a mounted Iguanodon, I’m always amazed at how big they are.

Stenopterygius quadriscissus - Gets in under “I” because it’s an ichthyosaur. Not a dinosaur, but I like how potbellied it looks.

Isisaurus colberti - a titanosaur named after the Indian Statistical Institute? Yes, please.

Incisivosaurus gauthieri - look at those teeth!

Ichthyovenator laosensis - that is a seriously weird looking dinosaur, what with its split sail and all. It’s from Laos, which you don’t see very often.
