The Baatara Gorge Waterfall or Three Bridge Chasm in Tannourine, Lebanon was carved out of ancient limestone over millions of years by winter meltwater.
The waterfall, which is fed by meltwater from Mount Lebanon, falls 250 meters into the chasm’s depths past 160-million-year-old limestone from the Jurassic period. Experiments carried out with flourescent dye in 1988 indicated that the water from the chasm emerges from underground at a spring in the nearby town of Mgharet al-Ghaouaghir.
Few of the dinosaurs depicted in “Jurassic Park” are from the Jurassic period. More accurately, it would be entitled “Phanerozoic Park,” but this name was taken by a city park in Phanerozoic, Michigan.
The discovery of this “first bird” from the Jurassic Period Germany in 1861 ignited the idea that birds descended from dinosaurs. Despite its name, Archaeopteryx likely couldn’t fly and spent most of its time on the ground and in trees.
How does a fossil that was illegally smuggled out of China
end up on display in Pittsburgh?
This feathered dinosaur fossil of an Anchiornis huxleyi from the late Jurassic Period is currently at Carnegie
Museum of Natural History in Pittsburgh on loan from a museum in China.
U.S. Immigration and Customs Enforcement’s Homeland Security confiscated this fossil from a dealer who tried to
illegally smuggle it out of China.
Carnegie paleontologist Matt Lamanna helped Homeland Security
Investigations identify the fossil as a feathered predatory dinosaur from
northeastern China. It was returned in 2015, but the Chinese government loaned the fossil to the museum where it will be on display until it is returned to the Geological Museum of China in Bejiing.
Castorocauda lutrasimilis catching breakfast. I’m not sure about the hind leg, but I was too lazy to change it.
Castorocauda was a semi-aquatic docodont that lived about 164 million years ago, during the Jurassic period, in what today is Inner Mongolia. It was a piscivore, that also supplemented its diet with invertebrates.
It was mammaliaform, but not a mammal.
It could reach a little over 40cm in length, and between 500 to 800g in weight.
The name Castorocauda lutrasimilis means beaver-tail similar to otter.
The holotype preserves extensive coat of fur, and also small scales/scutes on the tail. The tail was also covered in sparse hair.
day 26, accurate dinos dressed as inaccurate ones, with the return of the misfit raptors! the dilophosaurus is pretty proud of his costume, while the pegleg velociraptor sort of misses his batman outfit. @a-dinosaur-a-day
About the size of ravens, these prehistoric animals lived 145 million years ago during the Tithonian stage of the late Jurassic period. Their wing and tail feathers were similar to those of modern birds, suggesting at least some ability to fly or glide. The shape of their teeth indicates that they were probably carnivores and may have eaten small reptiles, amphibians, mammals, and insects. Twelve specimens have been found in Germany. When the first specimen, a single feather, was discovered in 1861, it was thought to be a hoax. Though there has been some scientific controversy over whether to classify them as birds or not, they were one of the first fossil discoveries to show a connection between modern birds and other dinosaurs.
Note: I’ve tried to keep this reconstruction of the Archaeopteryx as accurate as I can, but I definitely used my imagination to fill in some of the details.
I want to thank everyone again for your nominations and votes for my 1,000th bird! There was a great response and the voting got very close. It’s hard to believe I’ve made it to 1,000 and you’ve all been a big part of that. I’m grateful to everyone who has liked, followed, requested birds, or shared their bird stories or photos with me.
