Is This Shell Rot?

Hello, I just adopted this tortoise 2 weeks ago, and it’s shell looked a bit odd to me. There is a small crack where the reddish- orangish spot is. Please help explain.

No. Not shell rot. Looks like an old scrape through the keratin (scute) layer. Nothing to worry about.

Thank you so much.
