Hello everyone, greetings. I recently bought some fossil leaves. I contacted the seller and was surprised that the fossils were from here in Nicaragua, as I didn't know there were fossil sites here. I did not find information in pbdb navigator of the exact place where the seller found them since he collects them and found them himself, but in some studies on the net I found that the area of discovery is in the Brito Formation, a sector that covers a large part from the country's Pacific and dates from the Eocene, that is, from about 56 to 34 million years ago, which coincides with other description studies of some mammals found in this study area that I was able to read. My question is, is there any way to identify the leaves with a specific plant? I still haven't confirmed if what the seller told me is true that they are from here, but he assured me that they are, so much so that he offered me to go to the place where he found them, which I will probably go to in January next year to verify it on my own. I leave photos of the leaves that I took. These days I'll probably buy two more pieces from him that I also found from the seller in the same place.

So found a lot of fossil shells and fossil oyster shells in the limestone at canyon lake. Upon further inspection I found this hidden on lower corner. Is it a plant imprint?

From the album: Carboniferous Plant Fossils in My Collection
This is another view of the same Trigonocarpus, this view showing the open end of the seed. Seeds of seed ferns - this was probably from Medullosa - had open ends to allow pollen to enter. It is thought they were fertilized by pollen when they dropped into the water although a few paleobiologists believe insects may have pollinated them through the opening. Also why were the seeds encased in a fruit like covering (like avocados)? To be consumed by creatures that lived in the shallow swamp water?-
