    Glossoptris-branch

    This is a fossil of a Glossoptris tree branch. What makes this fossil interesting is at the top right of the photo, the formation of a limb, or new smaller branch can be seen. The other small hole on the lower right may be the result of a burrowing or boring insect that could have infested the plant or been the burrow of insect larvae. This can give an indication as to the health of the parent trees and the invertebrates that this environment may have supported.

    Glossopteris Leaf

    Glossopteris Leaf

    Glossopteris is the largest and best-known genus of the extinct order of seed ferns known as Glossopteridales. Glossopteris was a dominant plant throughout the Permian and much of the Illawarra Coal Measures are made up from the deciduous leaves that the plant dropped in the cooler seasons. They disappeared in almost all places at the end of the Permian. This example is of a leaf that is apparently similar in appearance to a tongue, the name Glossopteris comes from the Greek word ‘glossa’ which means tongue. Specimen from the Illawarra of NSW.

    Glossopteris Vertebraria

    Glossopteris is the largest and best-known genus of the extinct order of seed ferns known as Glossopteridales. Glossopteris was a dominant plant throughout the Permian and much of the Illawarra Coal Measures are made up from the deciduous leaves that the plant dropped in the cooler seasons. They disappeared in almost all places at the end of the Permian. This example is of part of the root system and is know as vertebraria, similar in appearance to a backbone which is why it was given this name. Specimen from the Illawarra of NSW.
