3 Areas Where the Most Dinosaur Bones Have Been Found

It’s hard even to fathom what it was like when dinosaurs were the chief inhabitants of the world. Fossils, of course, bring us a connection to these times, and they provide scientists with a way to theorize about what the world was like. If you nerd out about fossils and dinosaurs like we do, read on to learn about the three places where the most dinosaur bones have been found.

While humans find dinosaur bones all over the world, there certainly are hot spots where a higher density of these ancient treasures reside. North America is one of them. The different kinds of fossils are as numerous as you can imagine. But here are some examples of fossils in North America and where you can go to see them for yourself.

The Precambrian Period is the first period we recognize, and there are plenty of Precambrian fossils in North America, according to the Smithsonian. This era of Earth’s history involved a lot of microorganisms, algae, and soft-bodied species such as worms and jellyfish. A great place to see Precambrian fossils in the U.S. is at the Grand Canyon. There you can see algae fossils that are over one billion years old. Glacier National Park in Montana also has fossilized evidence of cyanobacteria dating back 1.5 billion years, as well as stromatolites.

Ancient multi-celled organisms are cool, but you might be wondering where you can see some actual dinosaur bones. Guadalupe Mountains National Park in Texas is a great place to see fish-like fossils and the predecessors to snails from the Permian Period. From the age of mammals — the Cenozoic period — you can spot ancient crocodiles and an animal similar to our modern-day hyenas at the John Day Fossil Beds in Oregon. And the Florissant Fossil Beds in Colorado have one of the most diverse displays in all the world. There, you can find a prehistoric rhinoceros and the first-ever discovered fossilized butterfly.

The vast collection of fossils found in Argentina is one of the country’s claims to fame. One example is Saltasaurus Loricatus, a small sauropod from the Late Cretaceous Period. This discovery, made in 1980, was a big deal in the world of paleontology because it was the first evidence of hard bone plates on the back. These plates operated like an armor of sorts. This dinosaur was an herbivore that was about 12 meters long. Scientists propose it could stand on its hind legs to eat leaves higher up in the trees.

Other treasures from Argentina include the fossils of Noasaurus Leali. This dinosaur looked like a small velociraptor similar to the ones found in North American and China, although it’s an entirely different species. It had sharp talons and teeth — which are definitely the characteristics of a carnivore. A rancher discovered these bones in San Juan in 1958, in what is now known as the Ischigualasto Formation.

For those wanting to travel to Argentina and see fossils for themselves, the Ischigualasto Formation is a great place to start. It’s now a regional park, and visitors can see the fossils still in the ground. Argentinians have also done a great job of providing fossil experiences in a museum setting that still feels authentic. One example is the Ernesto Bachmann Dinosaur Museum in El Chocón. This museum has replicas of fossils as they were found in the ground. They also have tools used by paleontologists on display so visitors can see what archaeological digs are like. There are other museums and parks in Argentina, as well, that educate visitors about the impressive fossils found in this country.

China is a massive country, and there have been fantastic fossil finds throughout the land. One of these places is the Qingjiang River, where paleontologists have found evidence of 101 different species along the river banks, and over half of those were new to science. The site was first discovered in 2007, but paleontologists have been busy exploring it ever since. They’ve found species as old as the first animals in the Cambrian Period. Chinese paleontologists and scientists around the globe are hoping Qingjiang will become a UNESCO World Heritage Site to protect these incredible findings.

A fossil hotspot in China that is already a UNESCO World Heritage Site is the Chengjiang Fossil Site. Chengjiang is located in the Yunnan Province and also has a vast collection of Cambrian Fossils. While there were many mining operations near the site, they’ve been shut down. The sites are starting to be rehabilitated so that further fossil records don’t get destroyed.

The Inner Mongolian Autonomous Region is another place in China rich with fossils. It’s even known as “Dinosaur Town,” and it has an abundance of Ankylosaurus and Ceratopsian fossils. Something unique about these fossils is that there’s evidence of all ages of creatures, from newborns to mature adults. Scientists in China are constantly discovering new fossil areas that are in urgent need of excavation.

Scientists discover body’s protection shield

Scientists have discovered a way to manipulate the body’s own immune response to boost tissue repair. The findings, published in Current Biology today, reveal a new network of protective factors to shield cells against damage. This discovery, made by University of Bristol researchers, could significantly benefit patients undergoing surgery by speeding recovery times and lowering the risk of complication.

When a  is damaged, (either accidentally or through surgery), the body quickly recruits  to the injury site where they fight infection by engulfing and killing invading pathogens, through the release of toxic factors (such as unstable molecules containing oxygen known as “reactive oxygen species” e.g. peroxides). However, these bactericidal products are also highly toxic to the host tissue and can disrupt the repair process. To counteract these  the repairing tissue activates powerful protective machinery to “shield” itself from the damage.

Now, researchers from Bristol’s School of Biochemistry studying , have mapped the exact identities of these protective pathways and identified how to stimulate this process in naïve tissues.

Dr. Helen Weavers from Bristol’s Faculty of Life Sciences, and the study’s lead author, explains: “In healthy individuals, injured tissues normally quickly repair themselves following damage. Within a healing skin wound, a stress-response is activated that recruits , which in turn release a multitude of bacteriocidal factors, including  (ROS), to eliminate invading pathogens.

“In this study we used translucent fruit flies to watch wound repair live as it happens and follow the behavior of the recruited immune cells. In doing so, we uncovered a network of protective pathways which shield tissues from inflammatory damage and make repairing tissues more ‘resilient’ to stress. We also demonstrated that ectopic activation of these pathways further enhanced tissue protection, whilst their inhibition led to significant delays in wound closure.

“Now we know their identities and how they are activated, we hope to develop ways to stimulate this protective machinery in patients prior to elective surgery.”

The findings have clear clinical relevance to patients because therapeutic activation of these cyto-protective pathways in the clinic could also offer an exciting approach to ‘precondition’ patient tissues prior to elective surgery.

Dr. Weavers added: “We are now uncovering even more ‘resilience’ pathways that help to protect our body tissues from stress, both at sites of wounding and in other vulnerable organs that are often exposed to similar stressors. Since we find that the protection machinery is activated by the same pathways that also initiate the inflammatory response, we think the resilience machinery has evolved as a fail-safe mechanism for tissue protection each time inflammation is triggered.

Four personnel of a police station in Manipur, which was awarded the best police station last month, were arrested and suspended for their alleged involvement in connection with the seizure of contraband drugs, sources said on Sunday.

Director general of police (DGP) LM Khaute issued a suspension order against the inspector while Tengnoupal district’s superintendent of police Th Vikramjit issued similar orders against the three other police personnel, including an assistant sub-inspector.

Khaute, in his order dated November 14, said a disciplinary proceeding is being contemplated against the inspector for his “grave misconduct and dereliction of duty.”

Inspector Letkhohao Vaiphei, assistant sub-inspector T Paominlun Haokip, head constable Md Khalilup and constable (driver) Luckson Kom are from the Moreh police station, which was awarded the best police station during the 128th Manipur police raising day on October 19.

Police sources said the four personnel were arrested in connection with their alleged involvement in the seizure of 34 boxes containing Ketamine injection bottles from a house at Moreh, a commercial town bordering Myanmar on November 12.

Th Vikramjit said a case has been registered for investigation.

“It is early to comment anything as the case under investigation,” the SP said over the phone from Tengnoupal district.

Letkhohao was remanded into judicial custody till November 20 after being produced before the court of the special judge of the Narcotic Drugs and Psychotropic Substances, Manipur on Saturday and the three others till November 18, according to sources.

Julian Assange: Sweden drops rape investigation

Julian Assange: Sweden drops rape investigation

Prosecutors in Sweden have dropped an investigation into a rape allegation made against Wikileaks co-founder Julian Assange in 2010.

Assange, who denies the accusation, has avoided extradition to Sweden for seven years after seeking refuge at the Ecuadorean embassy in London in 2012.

The 48-year-old Australian was evicted in April and sentenced to 50 weeks in jail for breaching his bail conditions.

He is currently being held at Belmarsh prison in London.

The Swedish investigation had been shelved in 2017 but was re-opened earlier this year following his eviction from the embassy.

In June, the then UK Home Secretary, Sajid Javed, formally approved an extradition request from the US where Assange is wanted on 18 counts related to the mass leak of American secrets.

What did the prosecutors say?

Deputy Director of Public Prosecution Eva-Marie Persson took the decision to “discontinue the investigation regarding Julian Assange”, the Swedish Prosecution Authority said.

“The reason for this decision is that the evidence has weakened considerably due to the long period of time that has elapsed since the events in question,” it added.

Ms Persson said: “I would like to emphasize that the injured party has submitted a credible and reliable version of events.

“Her statements have been coherent, extensive and detailed; however, my overall assessment is that the evidence situation has been weakened to such an extent that that there is no longer any reason to continue the investigation.”

The prosecutors said the decision had been taken after interviews with seven witnesses in the case.

What was the Swedish investigation about?

Assange was accused of rape by a woman and sexual assault by another one following a Wikileaks conference in Stockholm in 2010. He has always denied the allegations, saying the sex was consensual.

He also faced investigations for molestation and unlawful coercion, but these cases were dropped in 2015 because time had run out.

This comes after police said the demonstrators inside the Polytechnic University in Hong Kong had no option but to come out and surrender. The protests began peacefully in June and were sparked by proposed legislation that would have meant criminal suspects could be extradited to the mainland. Although the bill was withdrawn, the protests had broadened into a resistance movement against the territory’s government and Beijing.

Many of the protesters wear masks to shield their identities for protection.

China’s ambassador to Britain accused the UK and the US of meddling in the country’s affairs and warned that the Chinese government “will not sit on our hands” if the Hong Kong situation “becomes uncontrollable”.

Cheuk Hau-yip, the commander of Kowloon West district, said: “These rioters, they are also criminals. They have to face the consequences of their acts.

“Other than coming out to surrender, I don’t see that there’s any viable option for them.”

China’s ambassador to Britain Liu Xiaming has said that China has the “resolution and power” to end Hong Kong unrest amid protests.

Liu said that the People’s Liberation Army could be deployed in Beijing, warning: “They are already there in the Hong Kong garrison. They are there to show sovereignty and are responsible for defence purposes.

“If the situation becomes uncontrollable, the central government certainly would not sit on our hands and watch. We have enough resolution and power to end the unrest.”

This comes as China has denounced a Hong Kong court ruling declaring the government’s mask ban unconstitutional.

This decision has been seen as “seriously weakening” the power of the Hong Kong chief executive.

Chris Tang, Hong Kong’s new police commissioner, said in an interview that police alone are not able to end the violence.

Protesters believe the extradition bill is an example of Hong Kong’s eroding autonomy under Beijing.

They worry China is taking back the freedoms given to Hong Kong when the UK returned the territory to China.

Hong Kong police have laid siege to a university, pinning 800 students inside and threatened to use live ammunition on them, as the latest round of anti-government protests escalates.

China Is Concerned About HK Court Ruling

Central gov’t spokesperson expresses strong concern over HK court judicial review related to mask ban

Xinhua

A central government spokesperson on Tuesday expressed strong concern over the serious negative social impact of the ruling on the judicial review related to the anti-mask regulation by the High Court of the Hong Kong Special Administrative Region.

The Emergency Regulations Ordinance in force in Hong Kong was confirmed to be in accordance with the HKSAR Basic Law by the relevant decisions of the Standing Committee of the National People’s Congress in February 1997 and adopted as a law of the HKSAR, said Yang Guang, spokesperson for the Hong Kong and Macao Affairs Office of the State Council.

“This shows all the provisions of the ordinance are in accordance with the Basic Law,” Yang said.

The HKSAR Chief Executive in Council invoked the power under the Emergency Regulations Ordinance to put in place the Prohibition on Face Covering Regulation, which was an exercise of the Chief Executive’s functions in accordance with the Basic Law and relevant decisions of the NPC Standing Committee, he noted.

“The regulation has played a positive role in curbing violence and chaos since its implementation,” he added.

The Court of First Instance of the High Court of the HKSAR ruled that the provisions of the Emergency Regulations Ordinance which empower the Chief Executive to make related regulations under certain circumstances were inconsistent with the HKSAR Basic Law and that the main elements of the anti-mask regulation failed to meet the proportionality test.

“This is a blatant challenge to the authority of the NPC Standing Committee and to the power vested in the Chief Executive by law to govern. It will have serious negative social and political impact,” said Yang, adding that the central government will closely follow the development of this case.

The spokesperson expressed the hope that the HKSAR government and the judiciary will perform their duties strictly in accordance with the HKSAR Basic Law and jointly shoulder the responsibility of ending violence and chaos and restoring order.

Tomorrow will mark the 59th anniversary of the death of Richie Valens.

Most of us “non-millennials” have heard of Richie Valens. He was the one who brought us Donna and La Bamba before dying tragically in an airplane crash in 1959. I remember vividly singing along to both of these songs when I was a teenager a few years later. The line, “I had a girl, Donna was her name….” still echoes in my musical consciousness. For me the memories of Richie Valens are stronger than most. Here’s why:

Richie Valens was born Richard Steven Valenzuela on May 13, 1941 in Pacoima, California. Pacoima is just a stone’s throw from the town of San Fernando, where I grew up. I knew the turf well when I was a kid. It was a tough landscape that was…
