The fossil record of the family Pinaceae indicates that most genera first appeared in the high-
latitude and high-altitude regions of North America during the early Tertiary. In fact, six of the …

Since Pinus occurs in the Early Cretaceous (ca. 125-130 Ma), it probably had emerged from
a Pityostrobus complex by the Late Jurassic (ca. 140-135 Ma). Initial adaptation to seasonal …

Relationships of living and fossil Pinaceae were inferred using parsimony and Bayesian
inference of morphological characters and plastid and nuclear DNA sequences. When …

Discrete qualitative and continuous quantitative characters (" gap-coded") are used in a
parsimony analysis of the phylogenetic relationships of the pinyon pines. Cladograms …

Nineteen species of structurally preserved ovulate cones of the Pinaceae are known from
the Cretaceous. One of these belongs to Pinus, while the others contain anatomical features …

Pinus evolved in middle latitudes of the Northern Hemisphere in the middle Mesozoic. By
the late Cretaceous pines had spread east and west throughout Laurasia, attaining high …

Premise of the Study Pinaceae have a rich but enigmatic early fossil record, much of which
is represented by permineralized seed cones. Our incomplete knowledge of morphology …

The discovery of several hundred fertile and vegetative remains of three new species of
Picea A. Dietrich (P. suerdrupii, P. nansenii, P. palustris) from the middle Eocene (45 Myr) …

Pinus baileyi from the Paleogene of Idaho was initially related to the bristlecone pine P.
