Insects and Plants of the South-East Queensland Coal Measures (Triassic)
Many of the insects that lived in the Triassic forests are easy to recognise and could be compared with insects found in backyards today.
The insects at this time were similar in size to modern faunas. Most of the insects that have been collected are wings, or fragments of wings, with occasional body fossils. Thousands of insect wings have been collected in south-east Queensland, and new discoveries are continually being made by collectors. The most important and diverse Triassic faunas have been collected from the Mount Crosby Beds from the Esk Formation and the Ipswich Coal Measures in south-east Queensland.

Ginkgoites from the Triassic Period
Today Ginkgophytes are represented by a single living species, Ginkgo biloba, from China. This plant has the characteristic dissected foliage and male and female reproductive structures that distinguish this group of plants. While reproductive structures are rare, foliage that is similar to that of modern Ginkgoes are common in the Triassic Period and various genera and species have been named. Some fossil leaves seem indistinguishable from the modern Ginkgo and are referred to as Ginkgoites.
