The remaining Equisetales included the widespread Schizoneura, an upright herbaceous genus, with stems up to 2 meters tall and 2 cm wide (Behrensmeyer et al., 1992), which first appeared in the Carboniferous and continued into the Jurassic (Stewart and Rothwell, 1993).
However, the surviving order Equisetales was widely distributed and diverse during the Mesozoic.

These results compare favorably with those from the "extant only" analysis of morphological characters by Stevenson and Loconte (1996), in which the psilotophytes clade is attached to the stem at a node above the Lycopodiales and below the Equisetales (Stevenson & Loconte, 1996: [ILLUSTRATION FOR FIGURE 1 OMITTED]).
