I've seen deity pictures/idols (other than Vishnu)
like Surya Narayan and Durga Devi holding Disk and Conch Shell same like Vishnu...

I'm not much knowledgeable to understand why...so please shed some light on this...and are there any other deities other than Surya Narayan and Durga Devi with this similarities...
