Part 3- Interpreting fossil-bearing sedimentary rocks

Sample 12

Devonian (~380 million years) limestonefrom Rockhampton, central eastern Queensland

 

Sample 13

Cretaceous (100 million years) Allaru Formation, Richmond, central Queensland. This block is dominated, in terms of diversity, by Dimitobelus, a belemnite. Belemnites are an extinct group of free-swimming marine cephalopods, related to squids.

 

Sample 14

Pliocene (3.5 million years)- Chinchilla, southeast Queensland. The large fossil is an arm bone from a giant extinct kangaroo.

 

Sample 15

This block was collected from a middle Cambrian deposit from northwestern Queensland in July 2011 (believe it or not, but it was found on top of a mountain!). The block contains brachiopods (small marine animals that have shells) and trilobites (extinct marine arthropods that had an exoskeleton like insects, spiders and crustaceans) (see examples of the complete casts)

 

Sample 16

Cenozoic (last 66 million years), locality unknown
