I can't remember exactly where or when I acquired this , but I think I found in second hand store a few years back. Thought it was petrified wood but found images of eggs and thought maybe, it's not wood after all. Me and my rock hunting buddies would really like to know.

What is the Most Interesting Time Period to you?
Zenmaster6 posted a topic in General Fossil Discussion
I was curious about what peoples favorite Geologic Time period was. My favorites would have to be Early Cretaceous, because biodiversity was higher than previous times and we begin to see new life forms we might recognize today such as this 100 million year old bee I have. My second favorite is probably the Early Permian, entire Carboniferous and later Devonian because amphibians, therapsids, reptiles, sharks and plant evolution.
