Best COMPACT digital for macro

I am looking for a replacement for my venerable Nikon Coolpix 950,
which could focus as close as 2 cm and took great macro photos with
almost no effort on my part. My criteria are (2) better than the
950's 2 megapixels and (b) as small as possible. In the past I used
my Coolpix for research photos (fossils -- small osteological
features, teeth, etc.) and for fun macros (bugs, etc.) and I'd keep
using it except that the image quality just isn't up to snuff anymore
and it's kind of large for a pocket camera.

Second-hand Coolpix 990 or 4500 for macro work.
