Recent Articles About Fossil Hunting Laws and Regulations- Canada

Recent Articles About Fossil Hunting Laws and Regulations - Canada Dinosaurs

Below are a couple of articles about laws and regulations
for fossil hunting that raise either the same or similar issues
that concern collecting meteorites.

The articles, do not necessarily represent my views. If you need
comment about them, either post your comments as a reply to
this thread or correspond with the authors of the article.

Finally, an article that is unrelated to meteorites, but still quite
interesting.

https://eos.org/current-issues

(During the Ediacaran period more than a half billion years ago,
clay mineral coats likely shielded delicate remains, helping
them become exquisitely preserved in rock, recent experiments
suggest.)
