Why is the place Nova Scotia considered to be important in the study of ancient reptiles ?

 Ancient reptiles were trapped in the hollow stumps of primitive plants called Lycopsid. Nova Scotia is home to such hollow Lycopsid plants. Three genera or groups of reptiles were trapped in these tree stumps. 

Here are the names of the tree groups:

1. PAELEOTHYRIS

2. HYLONOMUS

3. PROTOCLEPSYDROPS

 This assembly of reptiles was lucky for the scientists. The ancestors of all the primitive reptilian groups were represented in this assembly.

Lycopsid
