Half Life Problem

A meteor  lands in Vancouver right on a grocery store located here on April 29 at around 12AM in the morning....There is an explosion of dumplings and frozen dim sum ....



The meteor fragment makes a huge crater 50 ft deep and in the rubble, you notice there are layers of shells. Amongst the shells there is the mystery specimen which I have shown you in class.  


Questions: 
1. What is the likely identity of the object?
2.  Where did it come from?
3.  How old is this sample?  It contains 78% of the ng of Carbon-14 compared to any living sample 
4.  Where is the location of the crater? What First Nations Territory is this area of the lower mainland?  

5.  How might this sample have ended up here? 

When you answer these questions, give the EVIDENCE for your answers.
