SELECTION OF UNUSUAL K-T BOUNDARY MATERIAL

You are looking at a bag of samples of material from the K-T Boundary of the Upper Cretaceous Period of Trochu, Alberta.  The bag contains lot of pieces and weighs 60gms.  What you see in the photo is what will be despatched.  Essentially carbon, this material also sometimes contains Cretaceous aged amber.  Further evidence of the impact of an asteroid as the cause of this last great extinction can be determined from the presence of the element Iridium found within this layer.  Iridium of this concentration does not form naturally on the earth, but is commonly found in celestial objects such as asteroids.  Imagine holding evidence of the greatest mass murderer our planet has ever known!
