Yes. While scientists generally dislike the term, it is used in pop science media and the average person can learn something important. While on one hand you have people holding out hope that the Loch Ness Monster and Bigfoot are going to be proven to exist someday (because it took a long time to discover the first coelacanth) , on the other, they understand that some organisms are more vulnerable to extinction because they are uncommon and live only in a small area.

There was a good book about living fossils released a couple of years ago, "Horseshoe Crabs and Velvet Worms" by Richard Fortey.

That last sentence is the best answer IMHO.

I appreciate this thread. It got me thinking about the topic in a new light. One of the many benefits of this forum. :-)

I will hunt up the book and read it. Thanks.

Those of us in the rest of the world outside of Texas will hunt down the book.

My goal is to leave no stone or fossil unturned.

I like to think positive. :-) BTW, it's on iBooks but costs 13 bucks. Yikes!

No library in Eagle Pass. This is a tiny border town. I prefer the Barnes & Noble loan, but will have to wait until our next trip to San Antonio. :-)

Well, we have a library, but it's closed for renovations....

The phrase "living fossil" arose to popularize organisms once thought to be extinct, but then rediscovered. "Living" and "fossil" are mutually exclusive terms, else wise.
