FOSSIL FOSSICKING HUGHENDEN AND DISTRICT

 
Approximately 16km north of Hughenden on the Kennedy Developmental Road, stop and try your hand at fossicking for fossils. The weathered mudstone rocks to the immediate north of Hughenden contain many fossils which date from the period 112 million years ago to 105 million years ago. They represent the remains of animals fossilised within two separate inland seas which flooded this part of the Australian continent at that time. The most common fossils found at the fossicking site are Belemnite guards. These weather out freely in the mudstone and can be picked up on small erosion surfaces and in the soil and range from 3cm to 9cm long.
 
These bullet or cigar shaped fossils are the internal skeleton from a type of squid which lived in the cool waters of the shallow inland sea. The Belemnite guard is composed of solid calcium carbonate and formed the counterbalance at the back of the Belemnite animal which was an active swimmer.
  
Other fossils known from the site include small bivalves and the ammonite Beudanticeras flindersi.
