Paleonet: Jurassic samaras (helicopter seeds)

[Yazbeck, Thomas]

Hello Paleonet,

I need help searching for answers on a real head-scratcher. I saw a social media post saying that the fossil in the photo was a Jurassic example of a "helicopter seed", aka a samara, from the Tiaojishan Formation. A modern example is presented for scale and comparison. I can't find anything online about this, although I found an older publication describing samara-like seeds from Siberian Jurassic gnetophytes. Can anyone point me towards an answer on what type of plant this might pertain to?
