Recently, Marie Angkuw mentioned that she had required a large, and very sweet example of Asterophyllites longifolius. She found this specimen at an antique mall. The fossil was part of an old collection. I wonder if it was the “oldest” antique at the mall?

Asterophyllites longifolius like its sister taxa Asterophyllites equisetiformis, was part of the foliage for the plant Calamites. Both species are known from Mazon Creek. A. longifolius and A. equisetiformis were named by Alexandre Brongniart in 1829.

Thanks for sharing, Marie!
