fossils Definition and 25 Threads

In all the replicas of dinosaurs that I have seen in museums and on tv and in movies (such as Jurassic Park), the dinosaurs have a greenish/blue skin without fur that makes the dinosaurs look like modern day reptiles. But I don't see how it is possible for any human to know what dinosaurs...

Here is a nice video (about 10 minutes) on Anomalocaris, a Cambrian animal known for its weird fossils. The video goes over how it was figured out from fossils (took a long time), how it worked as a predator (it could be two feet long and was the Cambrian's apex predator), how it...

Looking at the result of a great number of fossil expeditions, I understand how you can construct the full or partial skeletons of a number of different animals, you would be able to certainly identify certain bones as belonging to a distinct animal. That's great. you now know there were these...

Scientists have presented a stunningly preserved leg of a dinosaur. The limb, complete with skin, is just one of a series of remarkable finds emerging from the Tanis fossil site in the US State of North Dakota. But it's not just their exquisite condition that's turning heads - it's what these...

( https://www.nationalgeographic.com/magazine/article/dinosaur-nodosaur-fossil-discovery ) 1. Whats your favourite dinosaur? 2. Have you ever found a fossil (dinosaur or otherwise)? 3. Do you have any favourite non-dinosaur extinct creatures? 4. If you could travel back in time to see dinosaurs...

Ever wonder what is under the ground you are walking on? No, neither do I, usually. But, if anything, at least a record of the history of the Earth lies under your feet. https://phys.org/news/2017-12-subway-paleontology-la-unEarth's-fossil.html

What could this be?

Hey all. I've got a question regarding fossils. Each individual person is unique, and the variation between any two people can be significant. How large are the differences between individual humans compared to the differences between closely related species in our fossil record? How do...

There have been incidences where woolly mammoths were frozen in ice and as a result very well preserved with the brain and hair intact http://www.dailymail.co.uk/news/article-2812854/World-s-best-preserved-woolly-mammoth-goes-display-Moscow-39-000-years-trapped-glacial-ice.html. Neanderthals...

Hello! I read this post on Facebook and I am curious as to its validity and accuracy: 95% of the fossil record is made of plants. Shellfish & coral make up most of the rest while vertebrates (fish, amphibians, reptiles, birds & mammals) make only 1/4 of 1% of the fossil record & only 1 of...

How common is it to find fossilized insects entombed in Amber? I ask because there is a jewelry vendor here in Maui who claims that her amber jewelry encapsulating a variety of insects were created naturally, mined in the Baltic area and are thousands of years old. She sure has a lot of these...

Interesting finds. Continued... http://www.livescience.com/12883-plant-animal-mysterious-fossils-defy-classification.html

Hello! i was just wondering if anyone could help me with this, The rubidium isotope 87-Rb is a beta emitter with a half life of 4.9 x 10^10 yr that decays into 87-Sr. It is used to determine the age of rocks and fossils. Certain rocks contain a ratio of 87-Sr to 87Rb of 0.0100. Assuming there...

They didn't have Carbon 14 and I think fossil tree rings (dendochronology?) is a modern method so where did they get their millions of year from?

Here are a few of my fossil rocks I picked up outside, they are everywhere. I am going to post some large ones for detail, so sorry if you have to scroll. I was going to post this in Earth but images are disabled. Bear with me as I add pictures.

We went to see the exhibit of Chinese fossils at OMSI (Oregon Museum of Science and Industry) this last weekend, and I thought I'd share some photos. along with the fossils, they had some animatronic versions...

It's frightening to see that there are groups of people that want to hide reality from the populace. I hope the Museum has the guts to realize they have a responsibility to the public not to cave into fanatic groups. "Famed paleoanthropologist Richard Leakey is giving no quarter to...

We're using, Concepts in Modern Biology. On page 410, it says that layers of rock determine the age of a fossil, and few lines later that using a fossil we may determine the age of the layer. Does it work in this way that, they determine the age of the fossil using radioactive dating and then...

Hello, I'm just wondering, is it fine to predict the age of fossils older than 10,000 years with Carbon Datin? After all, I think nobody knows how much carbon-14 there was back then, and whether the animals consumed less or more carbon-14 than now. How exact are such long-term predictions?

I'm curious in the processes used to date the age of a human fossil, not in terms of how many thousands of years ago the human died, but the age of the human when they died. Are there any special processes that are used to determine this, or are humans mearly matched up in terms of degeneration...

Over how long is skeletal calcium essentially replaced by mineral depositation?

Are micro-organisms fossils on so-called Martian meteorite true? I think it is more likely contaminated by life on Earth...

This person has come up with a very good case for fossils on mars, well at least it's got me convinced. What do you think? http://home.cfl.rr.com/aichip/marsfoss.htm

are fossils really nonrenewable?
