Mesozoic
Microfossils
Triassic
Jurassic
A large sample of vertebrate bearing material that can preserve a classic Triassic fauna.
Reptile, amphibian and dinosaur material can be found in this material. They are not common,
but
Coelopyhsis teeth have been picked from this material. Each sample contains abundant
vertebrate remains, most of which are teeth.

Lower Lias - Lower Jurassic - £3/$5 (capsule).
Finally we are able to offer a microsample from the Jurassic. This foraminifera and ostracod
bearing matrix is from the Lower Lias
Oxynotum chronozone of England. Preservation is
superb. From each kilo of processed clay we are getting only 10g of microfossil concentrate -
that is a 99% reduction. It goes to highlight the work involved in obtaining microfossils. Quite
rich with many fossils per sample.

Hettangian, Belgium - Jurassic - £3/$5 (fine).
ostracod bearing matrix is from the Hettangian stage (lower most Jurassic) of Belgium.
Preservation is very good. Quite rich with many fossils per sample.
This is a coarser fraction from the same locality as that listed above. This fraction contains
larger microfossils, specifically gastropods and bivalves. Some foraminifera and ostracods still
remain. Preservation is very good. Quite rich with many fossils per sample.
