Elatocladus ? sp.

Fig. 5H.

Material.—A single fragmentary shoot from Nasiłów, ZPAL Pl 4/7/1.

Description. —The preserved part of the single shoot is ca. 13 cm long; leaf scars rhomboid, ca. 5 mm wide and 6 mm long. Leaves spirally arranged, either straight or slightly adaxially incurved, elliptic in cross section (about twice as wide as thick; no keel), with a distinct midvein, up to at least 4 cm long and 5 mm wide; the greatest width is at ca. one fifth of the length. The tip is probably acuminate.

Remarks.—This twig is quite different from the rest of the material described here in its much wider needles (5 mm compared to 2 mm in Cunninghamites squamosus for leaves of the same length of ca. 4 cm). There is also a distinct midrib (absent in C. squamosus , present in C. ubaghsii the leaves of which have, however, a very different form). This specimen is tentatively accommodated within Elatocladus Halle, 1913 , a very wide form genus , the species of which may belong to Taxodiaceae , Cephalotaxaceae , Podocarpaceae , Araucariaceae , Pinaceae , Taxaceae , or Cupressaceae ( Miller and Hickey 2010) .
