Locality Map



From Hollick (1930) (p. 114)

"Leaf ovate, tapering above to the apex and rounded below to the broad, cuneate base; margin entire; nervation camptodrome; secondary nerves eight on each side, irregularly spaced, leaving the midrib at varying angles of divergence, curving upward, thinning out, approaching and finally coalescing through the tertiary nervation along the margin."



From Hollick (1930) (p. 114)

"This leaf is described as a new species, although it might be regarded as a form of the variable species Diospyros primaeva Heer (1866) (p. 19, pl. 1, figs. 6, 7) from the Cretaceous of Nebraska, and as depicted by Lesquereux (1892) (p.109, pl. 20, figs. 1-3) from the Dakota sandstone of Kansas; and it may also be compared with Diospyros vancouverensis Dawson (1882 [1883]) (p.28, pl. 8, fig. 32) from the Upper Cretaceous of Vancouver Island. It is difficult also, to escape the idea that the leaves described and figured under the names Cornus holmiana - Heer (1883) (p. 36, pl. 62, fig. 12; pl. 64, figs. 6, 7) and Cornus thulensis Heer (1883) (p. 37, pl. 62, figs. 9-11) from the Patoot beds of Greenland, belong in the genus Diospyros rather than in Cornus, if the secondary nervation is correctly depicted, and that they are closely related to our species."
