A friend of a friend found this.
I Immediately reacted with “I know what this is” followed immediately by “I don’t know what this is”.

What animal has this?

One dorsal and one ventral spine attached to a vertebra. Vertebra oval is 1 cm by 1.3 cm. Distance between spine ends in 10 cm.

Look at these deer vertebrae. In the ballpark?

I wasn’t told where it was found, but the same person found fossil echinoderms so quite possibly near Beaumaris beach.

This image looks very like it. Fish tail (caudal) vertebra of bony fish.

But which fish?

Has to be big, 10 cm or more top to bottom of tail. Trying the field guide “Melbourne’s urban wildlife”.
And a teleost, not shark or ray.

Possibles may include:
leather jacket, flounder, barracouta, stargazer, mullet, scalyfin, perch, sea sweep, mado, bream, snapper, salmon, mulloway, taoior, trevally, beardie.

Most of those would have to be exceptionally large to have a vertebra this size.
