Dinosaur bones sandpit

[kelli]

I’m keen to make a 1m x 1m sandpit with a concrete floor like this one. Any ideas how to make the impression of dinosaur bones?

You just need a mould @kelli. I'd probably make them out of plaster, but you could also use concrete.

Thanks for the link. I thing I will use concrete so it lasts.

@kelli Nice little project!

Semantics but you should use cement/mortar rather than concrete so you don't have any aggregate in the mock-fossil. Will give you a smoother (and safer) finish.
