See if so is the case you have to file an reply.to show cause notice and present before the adjudicating authority for personal hearing further the substantive record of the fossile needs to be filed along with reply that the fossil doesn't belong.to any of the animal which endangered and prohibited under treaty and act.
Further on such import prior permission is required anything related.to animal origin is imported a prior permission from wildlife authority is required that it effect no animal pollution in original country and no violation of treaty.
Now since show cause is issued a evidence regarding same that it is fossil and no animal was harmed no treaty is violated so it is not liable for confiscation and penalty should not be imposed.
