Elephant poachers are hard at work in Africa, and carbon dating proves it

A Hong Kong court has convicted two people of illegally possessing ivory chopsticks after radiocarbon dating proved the items were produced after and therefore unlawful, the government said Wednesday. Domestic trade in ivory imported legally into Hong Kong before that year is not against the law if the seller has a government licence.

But the pair were convicted and fined after the dating process established the ivory was obtained after While environmental groups welcomed the use of forensic evidence, they condemned the light penalty.

Highlights: ▻ Dating ivory samples from the 20th century. ▻ Using direct CO2 absorption as an easy method with adequate performance for 14C determination.

Illegal ivory mostly from recent elephant killings

These ivory tusks were smuggled from Nigeria and bound for illegal markets in South East Asia, according to police in Bangkok. The illegal ivory trade is fuelled almost entirely by elephants that have been recently killed, say researchers who carbon-dated hundreds of ivory tusks seized by law-enforcement officials.

Some had wondered whether corrupt governments were contributing to the ivory trade by selling off old ivory, bit by bit, from stockpiles built up over years. Now, conservationists can concentrate their resources on protecting elephants from poachers, he says, rather than worrying so much about fighting government corruption.

Credit: Getty Images. More than 90 percent of ivory in large, seized shipments comes from elephants that died less than three years before, research shows. Scientists came to the conclusion by combining a new approach to radiocarbon dating for ivory samples with genetic analysis tools that gave conservationists a picture of when and where poachers are killing elephants. In June , the United States banned nearly all commerce in elephant ivory, which came 26 years after a ban on international trade in ivory.

Both measures aimed to curtail the widespread poaching of elephants, whose numbers have plummeted since the s. Poaching still kills an estimated 8 percent of African elephants each year, or around 96 elephants per day. Demand for elephant ivory and other illegal products derived from endangered animals has grown in Asia in recent years, opening a fresh battleground in the struggle against illegal ivory, even as US markets shut down.

Radiocarbon dating of ‘antique’ ivory being sold in European countries reveals that many are not antique at all. By Megan Shersby. Ivory items bought from a range of countries in Europe have been tested by the environmental group Avaaz and exposed to be modern ivory. The ivory pieces were all advertised with either no date or predating , but more than 47 per cent were found to be from after this year.

The date of is key as ivory is considered to be antique if it originates before then, and can be traded. A sample of ivory items were bought via antique dealers and private sellers, and then dated at the University of Oxford, to test the statements from European officials that there is no evidence of the legal ivory trade providing cover for illegal ivory.

When dating items, researchers are able to identify when the ivory was grown by the elephant, rather than when the animal was killed.

Woman killed from online dating There are just maybe, relationships marriage? Ivory coast are several dozen white women in abidjan and any destination. Have changed since the shantytowns of the date of the best prices. A try suing these scam girl from the dating effortless.

A Hong Kong court has convicted two people of illegally possessing ivory chopsticks after radiocarbon dating proved the items were produced.

Members of the unit are always happy to give advice on samples for radiocarbon dating. We have over thirty years of experience in the scientific aspects of the subject and have a staff who is able to deal with specifically archaeological or environmental questions. See the list of Staff for contact details. Radiocarbon dating is a powerful technique but selection of the best samples for dating is essential to successful application.

In all cases it is necessary to think about the relationship between the sample and the events of interest. Despite its strengths, the resolution of radicoarbon dating is limited and so it is well worth checking the resolution of the method at different time periods by simulations using OxCal. The choice of material for dating is an important part of any project and has a bearing on what kinds of statistical analysis will be possible at the end. It is always a good idea to discuss this with the laboratory if you are unsure.

Single entities samples which originate from a single organism are often the best type of sample for dating and in these cases identification to species or genus level is very useful. We can suggest people who may be able to help with this type of analysis. Sample size is another constraint in selection of samples for dating.

Illegal ivory found on sale in 10 European countries

All rights reserved. The new requirements do not apply to cut or carved ivory, nor do they apply to the tons of tusks already stockpiled. Starting July 1, anyone in Japan who wishes to register and sell a whole elephant tusk must first prove its age through carbon dating. More than that, officials believe that carbon dating will prove to be so burdensome as to dissuade private citizens—who hold untold numbers of tusks—from selling their ivory to dealers.

The carbon dating requirement will apply only to whole tusks registered after July 1, not to the tons of tusks already stockpiled.

The determination of the age of elephant ivory is a crucial aspect in the fight against illegal ivory trade. •. Absolute dating of the ivory allows, in forensics practice.

University of Utah researchers developed a new weapon to fight poachers who kill elephants, hippos, rhinos and other wildlife. By measuring radioactive carbon deposited in tusks and teeth by open-air nuclear bomb tests, the method reveals the year an animal died, and thus whether the ivory was taken illegally. It was published online the week of July 1 in the journal Proceedings of the National Academy of Sciences.

Not only can the method help wildlife forensics to combat poaching, but “we’ve shown that you can use the signature in animal tissues left over from nuclear weapons testing in the atmosphere to study modern ecology and help us learn about fossil animals and how they lived,” says Cerling, a distinguished professor of geology and geophysics, and biology at the University of Utah.

The method uses the “bomb curve,” which is a graph — shaped roughly like an inverted “V” — showing changes in carbon levels in the atmosphere — and thus absorbed by plants and animals in the food chain. The carbon was formed in the atmosphere by U. Those levels peaked in the s and have declined ever since but still are absorbed by and measurable in plant and animal tissues.

International agreements banned most trade of raw ivory from Asian elephants after and African elephants after

Tougher ivory law to come into force this year

The overwhelming majority of seized ivory from Africa comes from elephants killed in the past three years. The stark findings were reported by scientists who used radiocarbon dating on samples from elephant ivory specimens seized as part of 14 different operations from through The last couple of years saw a dramatic surge in traded ivory on the black markets, most of it destined to Asian markets.

We can tell how many elephants get killed thanks to modern surveillance measures and algorithms that extrapolate data. Using helicopters and cameras, conservationists and local authorities scour the savanna and count elephants one by one.

C dating methods can be used to determine the time of death of wildlife products. We evaluate poaching patterns of elephants in Africa by.

There are many misunderstandings about the use of ivory in antiques and we believe that the information given below will help provide more clarity. The poaching of elephants in the wild and the threat that this causes to the survival of the species is a very serious matter. We should make it absolutely clear that BADA members deplore the illicit market in ivory and are fully supportive of targeted and proportionate measures aimed at eradicating it.

It is not quite as simple as this, because most of the objects found in the UK today made from or incorporating elements of ivory were created many years ago and are part of our shared cultural heritage. These historical items are not derived from recently-poached ivory. Elephant ivory in large and small quantities has been incorporated into cultural artefacts for thousands of years.

As long ago as BC workshops in Mycenae were producing ivory boxes and furniture inlaid with ivory for export to the Greek mainland. In Egypt during the reign of Tutankhamun it was used as inlay in luxury goods, such as chests or head supports. Its use charts and reflects the changing culture of the world over many centuries and over widely differing cultural backgrounds.
