Solnhofen Zamites Cycad Fossil with Frond Tip
Spermatophyta, Class: Spermatopsida, Order Bennettitales
Time: Upper Jurassic
is 190 mm
Site: Solnhofen Limestone, Brunn,
Presented is an unusual and rare cycad plant frond from the lithographic
Solnhofen limestone deposits. According to my Solnhofen source,
only about 1-3% of these fossil cycad fronds have the tip preserved.
Evidently, due to seasonal adaptations the tip generally detached
from the frond.
The frond comes from the Brunn quarry, where most of the Solnhofen
plant finds have been discovered. Terrestrial plant fossils support
the premise that the Solnhofen Jurassic lagoons were adjacent to
a large land mass. According to my understanding, this quarry is
run by an educational institution. Once a year they sell a few
of their finds at a German fossil show to raise money to support
their institution. Of all the Solnhofen fossils collection sites,
fossil cycads are only discovered at this one quarry in Brunn.
This spectacular fossil comes from the lithographic limestone Solnhofen
deposits of Germany. These 150 million year old deposits are famous
for their exceptionally well-preserved organisms, the most famous
of which are the handful of specimens of the ancient bird Archaeopteryx.
