Hand Carved Ivory Dragon/Foo Dog/Lion Figure with orange stone inside

Found it buried in my yard when excavating for new drain pipe, it was under the stump of a large tree we removed. I live in a 120 year old home in the city of St. Louis. I am mainly interested in identifying what the figure may have been in whole form. I have done a bit of research and have not found any type of ivory carved figures with a gemstone/mineral interior like this one has.
