What is the world's oldest snake? Jurassic reptile found in UK
But the UK is also thought to be the home of the world's oldest snake, which dates back 167 million years to the Jurassic period.
The oldest snake in the world is the Eophis underwoodi, according to BBC Wildlife Magazine.
Fossil remains of the snake, primarily jaw fragments, were found in the Forest Marble Formation at Kirtlington Quarry in Oxfordshire.
Eophis underwoodi dates back around 167 million years to the Bathonian Age during the Middle Jurassic era.
BBC Wildlife Magazine said: "Prior to 2015, the oldest known fossil snakes were ~100 million years old.
"The discovery of Eophis extended the known geological range of snakes by more than 60 million years and suggested they may have originated at a similar time to most other major groups of scaly reptiles."
The snake is believed to have been alive around the same time as the Megalosaurus - a 6-metre long, meat-eating dinosaur, which also called a similar part of southern England home.
BBC Wildlife Magazine added that the Eophis was "far from a giant", only measuring around 25cm.
This is a far cry from the Titanoboa, which is the largest snake ever, at around 13m in length (which dates back to around 60 million years ago).

"It's also believed it had tiny hind limbs, like many other ancient snakes."

The adder has an average lifespan of up to 15 years, while the smooth snake can live for around 20 years.
The grass snake has the longest average lifespan of the UK's native species, as it can live for up to 25 years.

Ring of Fire volcano erupts for the first time for 600 years
Hiyah Zaidi Published August 5, 2025 3:29pm Link is copied Comments The megaquake that struck last week has led to a volcano erupting for the first time in 600 years, an expert says. The Krasheninnikov Volcano in Kamchatka Peninsula, Russia, which sits in the Ring of Fire, erupted into life on August 3, sending a plume of ash 3.7 miles (6 km) into the sky. No one was hurt, but the event was called historic. So, what happened? (Picture: Getty Images) In late July, the sixth-strongest earthquake ever recorded hit Russia's Kamchatka Peninsula. The quake was so strong it triggered tsunami warnings around the world, which affected the coasts of the US, parts of East Asia, parts of South America and New Zealand. The tremor reached a volcano in the Kamchatka region, and possibly contributed to this dormant volcano awakening (Picture: Mehmet Yaren Bozgun/Anadolu via Getty Images) One expert, Dr Alexey Ozerov, director of the Russian Institute of Volcanic and Seismic Sciences, told the Daily Mail there was a direct connection between the powerful earthquake and these eruptions. He said: 'We associate the eruptions with the earthquake, which activated magmatic centres, and "pumped" additional energy into them' (Picture: Sheldovitsky Artem Igorevich / IViS / Handout/Anadolu via Getty Images) Olga Girina, head of the Kamchatka Volcanic Eruption Response Team (KVERT), told Russian state news agency RIA Novosti: 'This is the first historically confirmed eruption of Krasheninnikov Volcano in 600 years.' And the team reported that clouds of ash travelled 46 miles from the blast. Around nine hours after the eruption, KVERT issued an aviation 'red alert' warning of significant levels of ash being sent into the atmosphere (Picture: Sheldovitsky Artem Igorevich / IViS / Handout/Anadolu via Getty Images) CNN reports that in the Telegram channel of the Institute of Volcanology and Seismology, Girina said that Krasheninnikov's last lava effusion took place in 1463, plus or minus 40 years, and no eruption has taken place since. Today (August 5), the channel reports that the volcano is still erupting, with emissions reaching six kilometers, and warns that emissions can reach up to 8 kilometers. The volcano has been assigned an orange (high) aviation hazard code (Picture: Getty) There have been no reports of injuries, and the local Nature Reserve said: 'The volcano's surroundings are volcanic wastelands, slag and lava fields without dense vegetation. There is currently no threat of a natural fire. The volcano's condition is being monitored. There is no threat to the lives of the reserve's employees, infrastructure or populated areas. Ash fall from the erupting volcano is observed in some areas of the Kronotsky Reserve' (Picture: Getty) There is an exceptionally high density of active volcanoes in Russia's Kamchatka Peninsula as it sits directly above the Ring of Fire, which is a 25,000-mile chain of volcanoes that stretches around the Pacific Ocean. The area is home to over 425 volcanoes, making up 75% of all active volcanic sites on Earth. This also includes some of the most destructive volcanoes ever to erupt, including Krakatoa, Mount Tambora, and Hunga Tonga-Hunga Ha'apai (Picture: Metro)

Breakthrough study finds it takes 3.5 years to diagnose dementia after first symptoms
It takes an average of 3.5 years to diagnose patients with dementia following their first symptoms, according to researchers. Early diagnosis and intervention is crucial in managing symptoms of dementia and developing an effective treatment course. However, experts fear that delays in vital treatment may occur due to confusion over symptoms, stigma and inconsistent approaches by medical professionals, among other things. Dementia is a condition that impacts's a person's thinking, memory, and behavior. Alzheimer's disease is the most common form of dementia, and more than 6 million Americans are affected by the progressive brain disorder. Symptoms include issues with memory, attention, communication, and vision problems. 'Timely diagnosis of dementia remains a major global challenge, shaped by a complex set of factors, and specific healthcare strategies are urgently needed to improve it. Other studies estimate that only 50 to 65 percent of cases are ever diagnosed in high-income countries, with many countries having even lower diagnostic rates,' Dr. Vasiliki Orgeta, an associate professor at University College London's Division of Psychiatry, said in a statement. U.K. researchers announced this week that it takes an average of more than three years to diagnose people with dementia following their first symptoms. But, early diagnosis is crucial to improve their quality of life later on (AFP via Getty Images) 'Timely diagnosis can improve access to treatments and for some people prolong the time living with mild dementia before symptoms worsen,' she added. The university's researchers also found that, for some, that diagnosis time may be even longer. For patients with early-onset dementia, it may take as long as four years. Early-onset dementia refers to dementia in someone younger than age 65. Those with frontotemporal dementia, the most common form for those under 60, are also were 'consistently associated with a longer interval to diagnosis.' The conclusions were the result of an analysis of 13 previously published international studies that reported data on 30,257 participants. The studies included medical records and interviews of patients or family members. Notably, while data on racial disparities was limited, one of the studies reviewed found that Black patients tended to experience a longer delay before diagnosis.

Nearly seven million Americans are affected by the progressive brain disorder (Getty Images) The authors noted that missed symptoms mistaken for aging, limited access to specialist care, language differences, and low public awareness could have an impact on diagnosis time. Orgeta said that their work highlights 'the need for clear conceptual framework on time to diagnosis in dementia.' 'To speed up dementia diagnosis, we need action on multiple fronts. Public awareness campaigns can help improve understanding of early symptoms and reduce stigma, encouraging people to seek help sooner,' she said. 'Clinician training is critical to improve early recognition and referral, along with access to early intervention and individualised support so that people with dementia and their families can get the help they need.' A test has recently been developed that scientists say could predict dementia up to nine years before diagnosis, with 80 percent accuracy. The study is the first systematic review and meta-analysis of global evidence examining time to diagnosis in dementia. It was published this week in the International Journal of Geriatric Psychiatry .
