Equicalastrobus is an extinct genus of plant related to horsetails from the late Carnian. It is known only from cones found in the Chinle Formation. Initially described as the genus Lycostrobus, it was variously assigned to the orders Lycopodiales and Isoetales before being assigned to the genus Equicalastrobus. It may represent an intermediate stage between Calamites and Equisetum.[1]
