Indonesia: 280 million years old fossil seed ferns found

By Isabel van Waveren, of the expedition researching 280 million year old fossil forests in Sumatra, Indonesia:

We find a place that we did not discover before, with some beautiful seed ferns (Sphenopteris).

After some time, we again find interesting fossil plants.

This time, it is another seed fern, Taeniopteris; however, unfortunately the rock is so brittle that it is difficult to cut a decent piece out of it.

Somewhat later, we try our hammer again, and this time we find something really special.

We find Macralethopteris, a third seed fern, which up to now we had mainly found along the Merangin [river].
