Proto-Elamite?
The Pashupati seal has an elephant, a water buffalo and a rhinoceros. Ancient Elam was centred in southwestern Iran. Elephants, water buffalos and rhinoceroses are not native to ancient Elam. BTW, they are native to India. Also, the figure is seated in a Yogic posture. Is Yoga also Elamite now? Seriously?
Your profile says you are a professor. I don't mean to sound rude, but your students deserve a refund. And seriously, Western universities need to improve their hiring practices.
This isn't Shiva. It's more likely adapted from proto-Elamite iconography, showing an Eurasian deity "lord of animals."
Indian history is amazing, wonderful, and fantastic -- It's well worth getting it right.
