While I've listened to many episodes, this is the first one that involved a prehistoric creature. I am always surprised by the creativity and freshness of each story.

However, I couldn't help but think Himan was indirectly or perhaps directly commenting on the role of Zoo's in our society. Maybe I'm reading too much into this but James talks about creating a national wildlife preserve while Richard talks about exploiting the creatures for money. Richard clearly is not concerned with the welfare of the creatures or science. He seems only to be concerned with the prospects for his own wealth.

There is also one last point that struck me as interesting. Richard (at 18:40) talks at length about duplicating the exact habitat of these creatures down to the caves and all. Nowadays this is common practice but was that the case in 1978 or was Himan ahead of his time?
