Imagine finding a mosquito that’s millions of years old and still has blood inside it! Sounds like something out of a movie, right? Well, that’s exactly what happened recently, and it’s got scientists buzzing with excitement.
Hi there! I’m here to tell you about an incredible discovery. Scientists have found a fossilized mosquito with blood inside it. You might think this happens all the time, especially if you’ve seen movies like “Jurassic Park,” but this is actually the first time ever! In fact, it’s only the fifth time in history that scientists have found a fossilized insect that fed on blood.
This mosquito was actually discovered 30 years ago by a geology student in Montana. After the summer program ended, the fossil was stored away in a museum basement and forgotten. It was only recently that it was “rediscovered” during a cataloging project.
So, does this mean we can bring back dinosaurs like in the movies? Unfortunately, no. There are a few reasons why this isn’t possible. First, the mosquito wasn’t found in amber, like in “Jurassic Park,” but in oil shale. Also, it’s only 46 million years old, which means dinosaurs were already extinct by then.
During the cataloging project, a volunteer noticed that the mosquito had stable red blood inside it. This is a big deal because it’s the first time we’ve ever found such a thing!
So, how did this mosquito end up in shale rock? Shale is basically mud that’s been squished together over millions of years. The mosquito might have had a meal and then got stuck in the mud, or maybe it drowned in shallow water during a rainstorm. Over time, the mud turned into rock, preserving the mosquito inside.
The blood inside the mosquito is a fascinating discovery, but not for the reasons you might think. We can’t tell what kind of blood it is because DNA doesn’t last that long. DNA has a half-life of about 521 years, which means after that time, half of it breaks down. After 46 million years, there’s hardly any DNA left!
Even though the DNA is gone, scientists have found that blood leaves a sort of “fingerprint” during fossilization. By using X-rays and mass spectroscopy, they can learn a lot about how blood-feeding insects have evolved over time. Isn’t that exciting?
Are you bummed that we can’t make a T-rex, or are you excited about what we’ve learned? Let us know what you think! Keep watching for more cool science news, and thanks for joining us today!
Imagine you are a time traveler! Create a timeline that shows the process of how the mosquito got fossilized in shale rock. Use drawings or digital tools to illustrate each step, from the mosquito’s last meal to its discovery. This will help you understand the fossilization process better.
Join a class debate on whether it’s possible or ethical to bring back extinct species like dinosaurs. Use the information from the article to support your arguments. This activity will help you practice critical thinking and public speaking skills.
Become a science reporter! Write and present a news report about the discovery of the fossilized mosquito. Include interviews with “scientists” (your classmates) and explain why this discovery is significant. This will enhance your research and presentation skills.
Conduct a simple experiment to understand fossilization. Use clay and small objects like leaves or shells to create your own “fossils.” Bury them in layers of clay and let them harden. This hands-on activity will give you insight into how fossils are formed over time.
Research how DNA degrades over time and why it’s impossible to extract dinosaur DNA from the mosquito. Create a poster or digital presentation to explain your findings to the class. This will help you learn more about genetics and the limitations of DNA preservation.

A mosquito was found fossilized with blood inside it. Dare I say that we might be seeing a dinosaur soon?
Hey everyone, I’m Trace, and you’re watching DNews. This week, humans rediscovered a fossilized mosquito with blood inside it. While “Jurassic Park” might have you thinking that we find these things all the time, in reality, this is the first time ever. In fact, it’s only the fifth time scientists have ever found a fossilized blood-feeding insect in human history.
I say “rediscovered” because it was actually found 30 years ago by a geology student who was digging around in Montana after a summer program ended. The fossil went into a box in a museum basement, adding to the list of discoveries that we found in the depths of science’s archives.
So, when are we getting dinosaurs from this fossil? Well, we’re not. There are a couple of things about this little insect that differ from the fictional world of Michael Crichton’s “Jurassic Park.” The mosquito was found not in amber but in oil shale, and it’s only 46 million years old—dinosaurs were long extinct by that time.
During a cataloging project, a volunteer discovered that the specimen contains stable red blood. This is the first time we’ve ever found that, so get excited!
So how did this mosquito end up in shale rock in the first place? Shale is essentially heavily compacted mud. It could be that the mosquito had a meal and got stuck in the mud, or perhaps it drowned in shallow water during a rain. Regardless, the mud trapped it and was compacted over millions of years, leaving behind the impression of this remarkable specimen.
The blood inside is a significant discovery, but not for the reason you might think. There’s no possible way to know what kind of blood the insect ingested—not because of the shale, but because DNA only has a half-life of 521 years. Even in perfect conditions, after 521 years, half of the DNA degrades. After 46 million years, only a tiny fraction of the DNA remains, so we’re pretty much millions of years late for that.
Even though DNA doesn’t survive the fossilization process, we now know that using X-rays and mass spectroscopy, scientists have learned that blood leaves behind a fingerprint during fossilization. This opens the door to understanding the evolution of blood-feeding insects and how they’ve evolved to today, which is quite exciting, right?
Are you disappointed that we can’t make a T-rex, or are you happy that we learned something new? Tell us your thoughts in the comments, and we’ll be sure to keep you updated on the latest in science news if you keep watching. Thanks for stopping by DNews today!

Mosquito – A small flying insect that feeds on the blood of animals and humans, often acting as a carrier for diseases. – Mosquitoes are known to transmit diseases like malaria and dengue fever through their bites.
Fossilized – Preserved in rock or other substances over a long period, turning into a fossil. – The fossilized remains of ancient plants and animals provide valuable information about Earth’s history.
Blood – The red liquid that circulates in the arteries and veins of humans and other animals, carrying oxygen and nutrients to cells and removing waste products. – Scientists study blood samples to understand how diseases affect the body.
Dinosaurs – A group of reptiles that lived millions of years ago, known for their large size and diverse species. – Dinosaurs roamed the Earth during the Mesozoic Era, long before humans appeared.
Amber – A yellowish, translucent fossilized tree resin, often containing preserved insects or plant material. – Insects trapped in amber can provide clues about ancient ecosystems and climates.
Shale – A type of sedimentary rock formed from clay and mud, often containing fossils. – Shale layers can reveal important information about the Earth’s geological history.
DNA – The molecule that carries the genetic instructions for life, found in the cells of all living organisms. – Scientists use DNA analysis to study genetic relationships between different species.
Evolution – The process by which different kinds of living organisms develop and diversify from earlier forms over generations. – Evolution explains how species adapt to their environments over time.
Geology – The science that deals with the Earth’s physical structure, history, and processes that have shaped it. – Geology helps us understand natural phenomena like earthquakes and volcanic eruptions.
Discovery – The act of finding or learning something for the first time, often leading to new knowledge or understanding. – The discovery of a new fossil species can change our understanding of evolutionary history.
