What is one example of geologic evidence supporting uniformitarianism that Darwin observed in his travel?
Darwin found much evidence supporting the ideas of uniformitarianism. For example, he found fossil shells of marine organisms high up in the Andes mountains.
What was Darwin's role aboard the HMS Beagle?
He was the "naturalist" and "geologist". The Captain (FitzRoy) wanted the compaionship of a man of his class, and needed a geographer and oceanographer, and so took Darwin (as a self financing passenger - Darwin was not paid!) on board.
What is fossil rich limestone?
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
What is the fossil on the opening scene of Journey to the Center of the Earth?
The fossil seen in the opening scene of "Journey to the Center of the Earth" is a prehistoric ammonite, a type of extinct marine mollusk that lived millions of years ago. Ammonites are known for their spiral-shaped shells, which are often preserved as fossils. The presence of this fossil sets the stage for the adventurous journey into the depths of the Earth in the movie.
Do all organisms become fossils?
No. The hard bones are more likely to form a fossil. The soft parts will degenerate over time. This is why most of the fossils from the Pre-Cambrian and Cambrian periods are mostly shells, not the actual animals that inhabited them.
What is the difference between sea shells and fossil shells?
Oh, dude, sea shells are shells you find on the beach, like the ones you pick up and pretend to hear the ocean in. Fossil shells are like ancient sea shells that have been buried for millions of years, so they're basically like the grandpas of sea shells. So, like, sea shells are for collecting, and fossil shells are for, I don't know, impressing your friends with your knowledge of ancient marine life.
What observations did Charles Darwin make about Galapagos tortoises?
turtles have shells....
Where did Darwin collects fossilized sea shells in mountain top caves?
Darwin collected fossilized sea shells in mountain top caves during his voyage on the HMS Beagle in the Andes Mountains of South America, particularly in places like Patagonia. He observed these fossils at high elevations, which contributed to his understanding of geological processes and the theory of evolution. The presence of marine fossils in such locations indicated that these areas had once been underwater, supporting the idea of gradual geological change over time.
Are Growth rings are found on both living and fossil clam shells?
No, growth rings are not typically found on living clam shells. They are commonly found on fossil clam shells and can provide information about the age and growth patterns of the clam when it was alive.
Can shells form a fossil?
Yes they can! In fact, shells are one of the easiest things to fossilize (the other is probably bone), and a majority of our knowledge on extinct, underwater invertebrates comes from their fossilized shells.

Why do you find shells in creeks?
The reason you find shells in creeks is beacause there once could have been an ocean there.
What did the shape of the turtle shells indicate to Darwin?
The shape of turtle shells indicated to Darwin that different species of tortoises had adapted to their specific environments. For instance, he observed that the domed shells of tortoises from wetter regions allowed them to store water, while the saddle-backed shells of those from arid areas were better suited for reaching higher vegetation. This variation supported his theory of natural selection, illustrating how species evolve traits that enhance their survival in particular habitats.
Can form a fossil?
Yes they can! In fact, shells are one of the easiest things to fossilize (the other is probably bone), and a majority of our knowledge on extinct, underwater invertebrates comes from their fossilized shells.
How did fossils become fossils?
It is the skeleton of an animal or shells pushed under rock for thousands of years and then it is a fossil.
What does most of the carbon in fossil fuels exist of?
carbon is an element, so "carbon" can't exist of anything. But the carbon found in fossil fuels are mostly from shells and dead animals or plants, after being exposed to imense heat and presure by stacking layers of sediment, plants and shells
What evidence indicates that the salt content of ancient oceans was about the same as it is today?
comparisons of modern seashells and fossil shells
