Something that I have always wondered about collecting fossils is it seems depending on the seasons and there are always better times to go. Of course, it entirely depends on the environment of deposition of the locality but in terms of areas like creeks or rivers that cut through formations, when is it really the right time to go? Of course there are variables like how much traffic is there, what times or weather does the area see, and temperatures. I can argue that spring can be the best time because fresh material and its been releasing fossils throughout the winter. On the other hand, I can argue that in the fall can be the best because of the amount of storms that must have occurred since the spring and material was being washed out all year. I believe there is correlation to higher temperature and more easily eroded material providing more fossils. I also believe in going when no one else will, like the winter. And there is always at the end of a big storm.
But no matter how much I like to speculate, one day you can go and have tremendous luck, and other days there just isn't as much material.
Thoughts?
