Hello Everyone.. New Member From San Bernardino CA
HideousCorrectness posted a topic in Member Introductions
Hello! My name is Elaine Scott. I am a new member to the forum. Exploring the mountains in the high desert and rock/fossil hunting is a hobby of mine. I have a small collection of interesting items. Some of which I will ask for help identifying, I look forward to feedback! I see there's soo much content to explore on this site I'm pretty sure I'll spend the next several hours (and many more in days to come) scrolling through it all. I hope everyone has a great day! -

Hello everyone, my name is Ray and I'm new here but not so new to fossil science. Although not an expert by any means and is why I'm here, to hopefully learn from those who are.

3D documentary I have been working on for the last 3 years is finally released! It is called Ancient Planet and tells the the story of Earth from the its formation in the Hadean Eon, until the end of the Proterozoic with its mysterious Ediacaran organisms. All 3 episodes are available for watching on Tubi service, which is completely free, just requires registration: https://tubitv.com/series/300007201/ancient-planet-trilogy?start=true

For the last year I have been working on the first part of my 3D animated documentary series about prehistoric Earth. The first episode will take you to Hadean eon 4.6 - 4 billion years ago and tell about the formation of our planet, moon, emergence of water and, finally the first life. The full documentary is pretty much done and is being edited at the moment (voice over, sound effects, etc.). Finally, here is the trailer for Part 1 (everything is CGI and done by me). Not sure yet about distribution methods. Anyways, here is the teaser:

I recently came across the young earth theory (the theory that earth is 10.000 years old and dinosaurs coexisted with humans and traveled with Noah and his ark) and of course i thought it was unfeasible but one common argument they keep having is why are we finding soft tissues, proteins and other biochemicals in fossils like triceratops, t-rex and other dinosaur bones of course that doesn't mean DNA BUT they shouldn't have been preserved because such biochemicals don't get preserved after so much time. Another one is that some old fossils are still close to the surface when they should be buried really deep. So what are your thoughts on these arguments, in my opinion this theory is ridiculous but i'd love to learn the answers. Thanks (PS sorry for asking that many questions these days its just that im new to the forum and have lots of questions)

A few weeks ago a member tried to estimate the number of ammonite fossils in the Earth. Here is a similiar calculation for diamonds: a quadrillion tons. I wonder if DeBeers has read this? https://www.cnn.com/2018/07/17/world/diamonds-under-earth-surface-trnd/index.html

Hi all. Zephyray (well now it's Zephyr) here again. Been a bit of an absence. I last posted almost three years ago. Unfortunately, I couldn't find the post to some fossil finds of mine. Ah well. http://www.thefossilforum.com/index.php?/user/4879-zephyray/ Anyway, at the time I was gathering information for a novel of mine, a visit to the middle Miocene, specifically the Barstovian. Well, now that novel is complete, and let me tell you what a lot of research went into it! Why the middle Miocene? That was when life on this planet went through a unique phase. When biodiversity was at its greatest. It must have been quite a world! “Lasting for millions of years, the mid-Miocene must have seemed a kind of endless summer” ~ Neptune’s Ark: From Ichthyosaurs to Orcas. David Rains Wallace For those sci-fi readers out there, those who long for adventure in an unspoiled world, Opalescence is for you. The book should be available for limited download, I hope in a week's time or so. It actually goes on sale February 1st, 2014 if everything goes as it should. You can get a glimpse now, though. Here is a link to a partial view: https://www.smashwords.com/books/view/390361 I also created a blog for the release of the book which you can see here. The About page will give you a synopsis. http://midmiocene.wordpress.com/ I hope you like Opalescence! Merry Christmas and Happy holidays, and best wishes for a happy New Year!
