A cylindrical permineralized conifer seed cone has been identified from the Officer Member of the Trowbridge Formation, near Izee, in east-central Oregon. The cone is preserved in a Middle Jurassic (Callovian) marine calcium carbonate concretion, associated with araucarian seed cones, conifer twigs and wood, cycad seeds, fern rachides, and lycopodialean remains and was prepared by the cellulose acetate peel technique. The specimen is abraded, 2.8 cm long and 1.3 cm wide, and consists of a cone… 
Diversity of Ancient Conifers: The Jurassic Seed Cone Bancroftiastrobus digitata gen. et sp. nov. (Coniferales)
TLDR
A third genus of anatomically preserved conifer seed cones has been recognized from a Late Jurassic deposit in northeastern Scotland, providing additional evidence for the diversity of stem group conifers that lived during the interval when most crown group conifer families originated.
Greater palaeobiodiversity in conifer seed cones in the Upper Jurassic Morrison Formation of Utah, USA
Although fossil conifer wood, leaves, and pollen have been known from the Upper Jurassic Morrison Formation of the Western Interior of North America for many decades, only a few conifer seed cones
X-ray Synchrotron Microtomography of a silicified Jurassic Cheirolepidiaceae (Conifer) cone: histology and morphology of Pararaucaria collinsonae sp. nov.
TLDR
This fossil develops the understanding of the dominant tree element of the Purbeck Fossil Forest, providing the first evidence for ovulate cheirolepidiaceous cones in Europe, and significantly extends the known palaeogeographic range of Pararaucaria, supporting a mid-palaeolatitudinal distribution in both Gondwana and Laurasia during the Late Jurassic.

Pararaucaria delfueyoi sp. nov. from the Late Jurassic Cañadón Calcáreo Formation, Chubut, Argentina: Insights into the Evolution of the Cheirolepidiaceae
TLDR
The discovery of 16 cylindrical conifer seed cones at the Estancia Vilán locality in the Late Jurassic Cañadón Calcáreo Formation of Chubut Province, Patagonia, Argentina, provides anatomically preserved specimens, allowing for the description of a second species of Pararaucaria (Cheirolepidiaceae), similar in general features to the type species, but has a specifically diagnostic combination of characters.
REPRODUCTIVE BIOLOGY OF THE CERRO CUADRADO (JURASSIC) FOSSIL CONIFERS: PARARAUCARIA PATAGONICA
TLDR
On the basis of anatomical and morphological features, specimens of P. patagonica are compared to members of both extant and extinct families of conifers including the Araucariaceae, Taxodiaceae, Pinaceae, Cupressaceae, and Cheirolepidaceae.
A New Species of Pityostrobus from the Lower Cretaceous of California and Its Bearing on the Evolution of Pinaceae
TLDR
A phylogenetic analysis using morphological data from the ovulate cones of all the extant and fossil taxa of Pinaceae, as well as those of Cryptomeria japonica, Sciadopitys verticillata, and Pararaucaria patagonica, was done and the idea that Pityostrobus represents an artificial assemblage of pinaceous taxa is supported by the analyses.
Coniferous Ovulate Cones from the Lower Cretaceous of Santa Cruz Province, Argentina
TLDR
These Patagonian cone scales appear to have some of the most ancestral characters in the family, and show that at that time, the taxodiaceaous Cupressaceae and the Cheirolepidiaceae still were well represented in southern South America.

TLDR
Analysis of the new Texas fossils refutes or seriously challenges many widely accepted hypotheses regarding the biogeography, structure, and paleoecology of F. ramosissima, which can no longer be considered a Potomac Group–endemic taxon.
Seed cone anatomy of Cheirolepidiaceae (Coniferales): reinterpreting Pararaucaria patagonica Wieland.
TLDR
Pararaucaria patagonica is assigned to Cheirolepidiaceae, documenting anatomical features for seed cones of the family and providing evidence for the antiquity of pinoid conifers leading to the origin of Pinaceae.
Permineralized Pine Cones from the Cretaceous of Vancouver Island, British Columbia
TLDR
Two abraded, cylindrical cone specimens found in calcareous concretions from the Cretaceous Spray Formation of Vancouver Island, British Columbia, were sectioned using the cellulose acetate peel technique and characterized anatomically, providing further evidence that the Pinaceae, like the angiosperms, were undergoing a rapid CRETaceous radiation.
