A new dinosaur fossil revealed that the show-off tendency in some birds, mostly peacocks, dates back to millions of years.

The new species, Ubirajara jubatus (the Latin meaning of the Lord of the Spear), was chicken-sized with a mane of long fur down its back and stiff ribbons projecting out and back from its shoulders, features never before seen in the fossil record. It is thought its flamboyant features were used to dazzle mates or intimidate foes.

An international team of scientists from the University of Portsmouth, and the State Museum of Natural History, Karlsruhe, Germany discovered the new species while examining fossils in Karlsruhe´s collection. The study was published on December 14 in the journal Cretaceous Research.

"What is especially unusual about the beast is the presence of two very long, probably stiff ribbons on either side of its shoulders that were probably used for display, for mate attraction, inter-male rivalry or to frighten off foes," said the study's lead author David Martill in a report published on the website of the Portsmouth University.

The ribbons are not scales or fur, nor are they feathers in the modern sense. They appear to be structures unique to this animal, which makes one ask: Why adorn yourself in a way that makes you more obvious to both your prey and to potential predators? "The truth is that for many animals, evolutionary success is about more than just surviving, you also have to look good if you want to pass your genes on to the next generation," Martill explained.

Modern birds are famed for their elaborate plumage and displays that are used to attract mates -- the peacock's tail and male birds-of-paradise are textbook examples of this. Ubirajara shows us that this tendency to show off is not a uniquely avian characteristic, but something that birds inherited from their dinosaur ancestors, as indicated this unique fossil.

Ubirajara jubatus lived about 110 million years ago, during the Aptian stage of the Cretaceous period, and is closely related to the European Jurassic dinosaur. It is the first non-avian dinosaur to be described from Brazil's Crato Formation, a shallow inland sea laid down about 110 million years ago.

In heavily forested Gabon, elephants are increasingly wandering into villages and destroying crops, angering the local population who demand the power to stop the critically endangered animals in their tracks.

"The solution to get rid of the pachyderms is to kill them," said Kevin Balondoboka, who lives in Bakoussou, a mere scattering of wooden huts in the sprawling, lush forest.

Villagers across the central African country live in fear of close encounters with elephants, whether on the road, going to wash in the river or especially in fields where they grow their crops.

Strict conservation policies have made Gabon "the refuge of forest elephants", Lea-Larissa Moukagni, who heads the human-wildlife conflict program at the National Agency of National Parks (ANPN) said, according to AFP.

African forest elephants, which inhabit the dense rainforests of west and central Africa, are smaller than their African savanna elephant cousins.

Poaching for ivory and loss of habitat have led to a decline over decades in their numbers and conservation groups now list the African forest elephant as critically endangered.

But that does not stop villagers from viewing the animals as a pervasive problem.

With a population of 95,000 elephants compared to two million inhabitants, the issue is a "real" one, said Aime Serge Mibambani Ndimba, a senior official in the ministry of the environment, climate and -- recently added -- human-wildlife conflict.

- 'Protecting humans or animals?' -

"What are the men in government protecting? Human being or beast?" Mathias Mapiyo, another Bakoussou resident, asked, exasperatedly.

"I don't know what the elephant brings them," he said.

Some worry their livelihoods will be stamped out.

"We provide for our children's needs through agriculture," Viviane Metolo, from the same village, said.

"Now that this agriculture is to benefit the elephant, what will become of us?"

William Moukandja, the head of a special forest brigade, has grown used to the anti-elephant complaints.

"The human-wildlife conflict is now permanent, we find it across the country, where we are seeing devastation from north to south and from east to west," he said.

Moukagni, from the national parks agency, said people's perception that there are more elephants than before was borne out by the figures.

"It is scientifically proven," she said -- but what has changed is that the elephants no longer shy away from villages and even towns.

To protect crops, the agency has experimented with electric fences, not to kill but to "psychologically impact the animal" and repel it.

Experts have looked into why the "Loxodonta cyclotis" -- the African forest elephant's scientific name -- is venturing out from the depths of the forest.

Climate change is affecting the plants and food available to the animals, Moukagni said.

But humans working the land that is the animals' natural habitat is another factor, while poaching deep in the forest also scatters herds, she said.

- 'Responsibility' -

The population of the African forest elephant plummeted 86 percent over 30 years, according to the International Union for Conservation of Nature, which has placed it on its red list of threatened species.

While they are still a long way from extinction in Gabon, Moukagni said the country had a dual responsibility "to keep this species alive for the world and for the sustainability of forests".

Last December, just three months after seizing power in a military coup, transitional President Brice Oligui Nguema publicly sided with "victims of human-wildlife conflict", in a shift from the conservation priorities of the previous government.

"I authorise you to kill these elephants... I am a humanist," he told the crowd to applause, also announcing he had asked for "all those jailed for killing elephants to be released without delay and conditions".

Jeremy Mapangou, a lawyer with the NGO Conservation Justice, said the message to the people was "strong" but added: "When the president said 'shoot them', he was referring to self-defence."

Hunting and catching elephants in Gabon is banned and carries a jail term. Ivory trafficking is also severely punished.

But in cases of self-defense, the killing of an elephant is permitted under certain conditions.

The weapon must comply with the law, the relevant administration must be informed, a report written and the ivory handed over as "state property".

Other measures permit the worst-affected communities to file a complaint and request "administrative hunting" to remove the four-legged troublemakers.

"But how can you file a complaint against an elephant?" Marc Ngondet, Bakoussou village chief, asked.

Mibambani Ndimba, wildlife management chief in the environment ministry, stressed that "the protection of elephants remains a priority".

Known as the "forest gardener", the mammals play a crucial role in the biodiversity and ecosystem of the forests of the Congo Basin, which has the second-biggest carbon absorption capacity in the world after the Amazon.

"We must provide help to Gabon so that we do not get to situations where the population rises up and wants to take justice into its own hands," Mibambani Ndimba said.

Otherwise, "elephant heads will roll".
