From all the articles and pictures I’ve seen about them over the years, I doesn’t appear to me that they are quite as rare as reported.
Correct.
Coelecanth found off coast of California
There are many "living fossils" (mostly dull stuff like mollusks) that are found deep in the fossil record and then found alive without showing up in upper strata. The Wollemi pine is another well-known example. Finding a dinosaur would actually be anti-climatic at this point.
I don't believe any dinosaurs are still around though. People don't understand the degree to which viable habitats have been surveyed by people all over the globe. It's one thing to identify a plant as a slightly different species or to identify a small mammal as a slightly different sub-species from those previously known, but a dinosaur would stand out. Not to mention their tracks, scat, physical remains when dead and so on.
No. I think it was in the 1930s when an archaeologist discovered that native people were catching and eating them. Someone had brought him one, and he was shocked to see it.
I was aware of the discovery in 1938 off the coast of South Africa, and am delighted to find out that they’ve found them off the coast of Indonesia too.
