I'm trying to remove a kitchen faucet, and I can't figure out how to remove the faucet with these weird 'elephant ear' brackets. Can anyone identify them or provide a suggestion on how to remove? Thank you!

Looks like it was a Costco faucet, and once I realized that the hex screw was covered up by mineral deposits, I cleaned it off and I was able to use the link below to get it off easily.
