This plate from  the Muddy Creek Formation of Montanna festures a nice fossil pine cone of Metasequoia .  The Fossil Metasequoia cone measures about 14 mm in diameter.

Metasequoia also known as  Dawn Redwood was initially only known in fossil records until a recent relic occurrence of this living fossil was found in China in 1941.
The recent species Metasequoia glyptostroboides is not permanently green
Short shoots of the primeval sequoia turn red-brown in color in winter, as in deciduous trees, and are thrown off.
