Yesterday my friend at work sent me this paper because she had heard of my interest in bones. This article features a graveyard – not of humans but of fossil lemurs and other fauna. An expedition of some flooded freshwater caves in Tsimanampetsotsa National Park, Madagascar was undertaken to investigate the paleontological potential of the caves.

On this preliminary investigation several species were identified including birds, reptiles, small mammals and large vertebrates and that this assemblage represents ‘a reasonable cross-section of the known extinct fauna found in the region of Tsimanampetsotsa National Park’ along with some species that are still living today. From this range of fauna discovered the most abundant were the giants lemurs and appears to be one of the most richest sites in Madagascar. 

As this expedition was conducted to explore the site no specific measurements or counts were made regarding the skeletal remains. However, future investigation may be able to shed light on past biodiversity in that area and the time period that they existed. I will try to keep an eye on for developments of this site in the future as it has great potential.

You can read the article here which also includes a video taken during a diving trip into the caves.
