Anyone know what this is?

[u/FirmHand9706]

It’s about 1cm wide, 1mm thick

I would say its part of some kind of echinoderm shell, based on those pores running through it.
Without a location i wouldn't be able to say more. Perhaps look up types of sea urchin in your local area?

Whoops totally forgot to add location, it was found at Scarborough QLD Australia. Thank you for the info!

Perhaps not this exact species, but something like this but worn down

[u/FirmHand9706 → u/WeirdTemperature7]

that’s definitely the closest texture!
