Permian Ammonites from West Timor

I have very few Permian aged fossils in my collection and even fewer that don't come from the US. Thus I was very happy to receive these next two Ammonites in an exchange with a friend, Laurent, in France. Both are from the Artinskian stage of the lower Permian and come from West Timor which is a part of Indonesia.

Sundaites laevis

Popanoceras sp. I like this one because it has been polished to show the internal sutures which separated the shell into hollow chambers. The pattern of mineral replacement is very nice and there are two small vugs with Calcite crystals as well.
