recently
Maoming City is also at a construction site near the Ninth Road of Youcheng In the downtown area
Discover a nest of fossil dinosaur eggs
This is Maoming following the discovery of dinosaur egg fossils in 2001
Rediscovered 20 years later
↓↓↓
Maoming City also found a nest of dinosaur egg fossils at a construction site near Youcheng Ninth Road in the city.
And in July 2019
Elementary school students in Heyuan, Guangdong Province, discovered 60 million-year-old dinosaur egg fossils
A total of 11 "stone eggs" were dug up.
Once again, let the "Hometown of Chinese Dinosaurs" successfully go out of the circle
Since 1996, when dinosaur egg fossils first appeared in Heyuan
Heyuan has become a fossil of dinosaur eggs worldwide
Mainly out of the land and collections
On April 9, the docent of the Guangzhou Museum explained the knowledge of dinosaur fossils to visitors. 7c filming
Access to information shows that in recent years
Guangdong Sanshui, Heyuan, Huizhou, Nanxiong, Maoming
There are constant news of dinosaur egg fossils
So tens of millions of years ago
Why did Guangdong become the home of dinosaurs?
What is the local geographical environment and ecological environment?
What are the types of dinosaurs that appear in Guangdong?
Q1: How to judge whether it is a dinosaur egg fossil?
Dinosaur egg fossils dating back tens of millions of years
How do researchers determine the identity of dinosaurs?
According to reports, eggshells will be weathered
Form a black line
Researchers can study the structure by slicing the eggshell
For example, whether the eggshell arrangement is honeycomb or fibrous
Infer whether it was a carnivorous or herbivorous dinosaur;
According to the content and structure of the specific metal elements of the eggshell
Its specific food composition can be judged
Thus making a judgment on the identity of the dinosaur
There is another important point of judgment
It is hidden on the rocky material that wraps the fossils
Red sandstone formations are necessary for the discovery of fossilized dinosaur eggs
According to experts
The geological structure of the red sandstone layer
It is the geological basis of the late Cretaceous period
Q2: Why did dinosaurs prefer Guangdong?
In addition to the recent discovery of dinosaur egg fossils in Maoming
In fact, Heyuan, Nanxiong and other places
They are all "big households" that have found dinosaur fossils.
Why did Guangdong become a dinosaur at that time
What about your favorite place to live?
Published in the Journal of Stratigraphy in February 1999, "Layers and Distribution of Dinosaur Eggs in Guangdong" introduced the main areas of known excavated dinosaur egg fossils in Guangdong.
According to reports, the northern part of the South China Sea was all land at that time
The territory of Guangdong is a basin where large and small plants flourish
It became a paradise for dinosaurs to live in
So, in some of the larger basins
Such as Heyuan Basin, Sanshui-Guangzhou Basin, Nanxiong Basin
Luoding Basin, Maoming Basin and other places
Dinosaurs lived the most moist
Therefore, most of the dinosaur fossils found in the province come from the above places
Q3: Why are there so many dinosaur fossils in Heyuan?
As the region with the largest collection of dinosaur egg fossils in the world
Back in 2004
Guangdong Heyuan is fossilized with 10,008 dinosaur eggs
Broke the Guinness World Record
Up to now, the collection of dinosaur egg fossils in Heyuan Museum has exceeded 18,000
It still has the highest number of dinosaur eggs in the world
According to the analysis, the source of the river in ancient times is likely to be a low-lying swamp
Natural conditions are very suitable for dinosaurs to thrive
Some geological experts also said that the earth's crust is constantly moving
Today's Sanshui-Guangzhou Basin is located on the alluvial plain of the Pearl River Delta
Therefore, the red sandstone layers where dinosaur fossils are hidden are buried underground
The source of the river is mountainous, and many red sandstone layers are exposed
Therefore, it is easier to detect

q4: What are the species of Guangdong dinosaurs?
Flying in the sky, swimming in the water
Dinosaurs come in all kinds
But what kind of dinosaurs lived in Guangdong
Is there a T-Rex in the movie?
Dinosaur egg fossils were found 30 years ago in Pingzhou, Guicheng, South China Sea.
According to public reports, dinosaur egg fossils have been excavated so far
Shapes are oval or round
Others are finger-shaped
In Guangdong, most dinosaur egg fossils are
The diameter is about 15 to 20 cm
Dinosaur egg fossils found in the north are on the larger side
Reach 30 to 50 cm
Maoming dinosaur egg fossils.
According to reports, there are currently 9 types of dinosaur egg fossils that have been fixed in Guangdong Province
There are 3 types of dinosaur fossils
Including oviraptorosaurs, ankylosaurs, theropods and so on
