the shell of a crab
the body of a jellyfish and the shell of a crab
which one though
Based on the question, the body of a jellyfish, the shell of a snail, and a dinosaur's backbone can all be excluded due to the absence of fossil records. Therefore, the answer is:
- the body of a jellyfish
- the shell of a snail
- a dinosaur's backbone
A fossil record is a collection of preserved remains or traces of ancient organisms, providing evidence of their existence. When trying to determine what can be excluded due to the absence of fossil records, we need to consider which ones would not have been preserved through the fossilization process.
In this case, we can exclude the body of a jellyfish because jellyfish have soft bodies that are unlikely to be preserved as fossils. Soft-bodied organisms, like jellyfish, do not have hard parts that can resist decay and withstand the fossilization process.
We can also exclude the shell of a snail because snails have shells made of calcium carbonate, which can dissolve over time, making them less likely to be preserved as fossils. Additionally, snails are not as commonly found in the fossil record compared to other organisms with better preservation potential.
On the other hand, a dinosaur's backbone can be included since dinosaur bones have been found in the fossil record. Dinosaurs had a robust skeletal structure, including backbones, which have a higher chance of being fossilized due to their durable nature.
Finally, the shell of a crab can also be included as it is made of a hard and durable material, providing a higher chance for preservation as a fossil.
So, based on the absence of fossil records, the body of a jellyfish and the shell of a snail can be excluded due to their low preservation potential, while a dinosaur's backbone and the shell of a crab can potentially be included.
