These are thrombolites – rocks that are porous and contain microbial communities that photosynthesize. I wouldn’t say that these are relatively small although you can find some which are bigger than an adult male. The fact of the matter is that they are extremely rare but Western Australia is lucky enough to have them in a few places.
This was taken down at Lake Clifton in Mandurah, WA, approximately ~100km south of Perth. It’s a very scenic drive once you get to Mandurah and there is also a scenic drive just around the corner from the entrance to Lake Clifton which I highly recommend as well.
I used this opportunity to test my new Xiaomi 360 degree 3.5K Action Sports Camera while I was at it. Yes, the clouds were amazing. I also posted another picture from this day on my Instagram which you can view by clicking here.
