Ibyka

Ibyka is an extinct genus of Iridopteridales, and a possible ancestor to horsetails.^[1]
The name comes from the poet Ibykos because the discovery of the fossil was due to the activity of construction cranes during the construction of the Gilboa Dam. ^[2][3] The probable relationships within Equisetopsida are shown in the cladogram below. The position where Ibyka would be added.^[4]
