The major taphonomic processes that control insect preservation in carbonate rocks
(limestones, travertines and nodules) are biological: insect size and wingspan, degree of …

Chitin is present in fossil insects from the Oligocene (24.7 million years ago) lacustrine
shales of Enspel, Germany. This result, which was obtained by analytical pyrolysis, extends …

Sponges are probably the earliest branching animals and their fossil record dates back to
the Precambrian. Identifying their skeletal structure and composition is thus a crucial step in …

Flash pyrolysis/gas chromatography (py/GC) and py/GC/mass spectrometry (MS) have been
utilized to characterize the cuticles of invertebrates chemically. Pyrolysis products have been …

Beetle exoskeletons contain chitin, a poly amino-sugar that is biosynthesized incorporating
hydrogen isotopes from diet and water. As the stable isotope ratios D/H (or 2H/1H …

The preservation potential of chitin in the marine environment is a matter of debate. To
determine the relative survival of chitin and other organic components, the shrimp Crangon …

Stable oxygen and hydrogen isotope analyses of fossil aquatic organisms, such as the
chitinous head capsules of chironomid larvae (Chironomidae: Diptera), are promising …

Studies of an unusual and diverse system of caves in coastal southern Jamaica have
yielded a paleoclimatic record associated with a fossil vertebrate record that provides useful …

The understudied locality of Tasgorosay tract, Karzhantau ridge in Kazakhstan offers an
interesting, yet very homologous array of fossil insects. The material used for this research …

The stable isotopic composition of fossil resting eggs (ephippia) of Daphnia spp. is being
used to reconstruct past environmental conditions in lake ecosystems. However, the …
