Flesh of a dead animal found at waimea beach

I was walking at the beach earlier today with my cousin and dog and we came across this as my dog was sniffing it. I thought it was some wood since theres a lot of sticks everywhere at waimea beach by the cottages but I took a closer look and its some dead animal. My cousin said it look like a cow but i don't know for sure, since it could be anything.

This post might get deleted but i'm gonna post it anyway since I'm curious to know what this is. This is the only close up angle I have.
