A scrappy family of mammals with unusual, mismatched features moved underground and, like living in a perpetual bomb shelter, managed to survive the mass extinction event 65 million years ago that wiped out the world’s non-avian dinosaurs. We know this thanks to new research on the fossil mammal Necrolestes patagonensis, whose name translates to “grave robber,” referring to its burrowing and underground lifestyle. The animal, described in the latest Proceedings of the National Academy of Sciences, had an upturned snout, a sturdy body structure, and short, wide legs.

It lived 16 million years ago, long after the dinosaur demise. But it was found to be related to another fossil mammal, Cronopio, which belonged to the Meridiolestida, a little-known group of extinct mammals from the Late Cretaceous and early Paleocene (100–60 million years ago) of South America.

Cronopio and Necrolestes share a number of features in common, including the fact that they are the only known mammals to have single-rooted molars. Most mammals have double-rooted molars.

The animals were so odd and puzzling, at least to modern eyes, that they mystified scientists for years.

Necrolestes is one of those animals in the textbooks that would appear with a picture and a footnote, and the footnote would say ‘we don’t know what it is,’” co-author John Wible of the Carnegie Museum of Natural History said in a press release.

For a long time it was thought that “grave robber” was a marsupial. Further analysis, however, found that Necrolestes actually belonged in a completely unexpected branch of the evolutionary tree believed to have died out 45 million years earlier than the time of Necrolestes.

This is an example of the Lazarus effect, in which a group of organisms is found to have survived far longer than originally thought. (“Lazarus” comes from the Bible story about how Jesus raised a man from the dead.)

“It’s the supreme Lazarus effect,” said Wible. “How in the world did this animal survive so long without anyone knowing about it?”

A good example of the Lazarus effect is the ginkgo tree, thought to be extinct until it was rediscovered growing in China in the 17th century.

The researchers believe that Necrolestes’s supreme burrowing adaptations are exactly what enabled it to survive for 45 million years longer than its relatives.

“There’s no other mammal in the Tertiary of South America that even approaches its ability to dig, tunnel, and live in the ground,” explained Wible. “It must have been on the edges, in an ecological niche that allowed it to survive.”

Killer whale and dog, video


From Discovery News:

When you combine the enthusiasm of a killer whale and playful romping of a swimming dog, the results are unpredictable. Luckily for us, someone captured their exchange and they get along just fine!

This video from New Zealand says about itself:

Encounter with Orcas at Matheson Bay, Leigh.

The free diver was on his way back in when he must have seen the Orcas and quickly got out onto the rocks. It seemed like there was at least 4 Orcas around him of which one was a mother with her calf.

The one Orca came very close to shore where the Labrador was busy retrieving sticks from the water. He saw the whale and quickly turned around and swam back to shore with the Orca following as far as he could go.

Charities slam MoD’s surgery on shot pigs

Monday 19 November 2012

Animal welfare groups attacked the Ministry of Defence today after it defended shooting live pigs to train army surgeons.

The pigs are shot by marksmen at a Nato training facility in Jaegerspris, Denmark, to replicate battlefield wounds and are then operated on by military medical staff.

Formerly known as Operation Danish Bacon, the practice has been described by animal rights groups as “impossible to justify medically, ethically and educationally.”

An MoD spokeswoman said: “This training provides invaluable experience, exposing our surgical teams to the specific challenges posed by the injuries of modern armed conflict.”

The MoD said although the practice would not be illegal in Britain, approval would have to be obtained on a case-by-case basis from the Home Office.

The government of the day suspended British participation in the surgical training exercises in summer 1998 after they were brought to the attention of ministers.

But the courses were re-instated after it was determined there was “no equally effective alternative” and that it was “entirely appropriate and, indeed, necessary” for military surgeons to carry out training on animals.

People for the Ethical Treatment of Animals described the procedure as “invasive and deadly” and claimed it would be illegal in this country.

It called for life-like dolls that “breathe” and “bleed” to replace the use of live animals.

Associate director for Peta UK Mimi Bekhechi said: “The overwhelming majority of the UK’s Nato allies do not shoot, stab and dismember animals for their military training exercises.”

The RSPCA said it was “upsetting that pigs were shot for surgeon practice.

“Pigs are highly intelligent animals and many people will be very distressed to hear about this,” it said.

“It is yet another example where animals pay the price of man’s inhumanity to man.

“We implore the military to explore the viability of alternative methods, and where these are found lacking, to invest in their further development.”

From The Independent:

Eighteen pigs were used in the most recent tests earlier this month, the Mail on Sunday reported.

They had circles drawn on their underbellies before a three-man sniper team fired shots intended to damage organs but not kill, the paper said.

Surgeons then treated them as they would battle zone casualties, reportedly keeping the pigs alive for two hours before they were put down.

Bird crime in Malta

Injured Pallid Harrier and hunter shooting at protected birds

Apr 5, 2010

Footage released by BirdLife Malta today revealed the targeting of rare and protected species over the Easter weekend, where one of the rarest birds of prey in Europe was seen struggling to survive gunshot wounds, and a hunter in Gozo was filmed shooting at protected birds in broad daylight by the side of a main road.

Big increase in illegal hunting in Malta – Raptors targeted

Shot protected birds doubled this autumn

November 2012, Malta – Since the opening of the autumn season on 1 September, BirdLife Malta has received 62 shot protected birds- nearly double the total of 33 shot protected birds recovered over the same period last year. This is the worst autumn hunting season since the organization started keeping detailed records of shot birds in 2007.

Birds of prey including Pallid harrier

Over 60% of the shot protected birds were birds of prey, including rare species in Europe such as the Pallid Harrier.

Furthermore during BirdLife’s international bird monitoring Raptor Camp the conservation organization recorded an additional 124 injured protected birds in flight with visible gunshot injuries, and a further 106 protected birds being shot at or shot down by illegal hunters.

Commenting on the present situation, BirdLife Malta Conservation Manager, Nicholas Barbara said “We have been witnessing widespread and commonplace illegal shooting and killing of protected species this autumn. The nearly 300 protected birds we witnessed being killed or received are just those we could record with our limited resources. We suspect that with the shot birds directly reported to the authorities and the unrecorded incidences, thousands of protected birds have been killed this autumn.”

Police overwhelmed

The flood of dead and injured protected birds received during the autumn hunting season has overwhelmed the Maltese authorities to the extent that the National Museum of Natural History, the Malta Police Force, as well as MEPA have no more capacity to store the carcasses of shot birds.

567 incidents of illegal hunting

BirdLife Malta alone recorded 567 incidences of illegal hunting at 40 different locations in Malta and Gozo during its Raptor Camp in September.

With a daily average of just 3 police vehicles observed patrolling the countryside, the mean response time to illegal hunting incidents reported to police by Raptor Camp teams was 50 minutes.

“All the evidence shows that illegal hunting is getting worse and that current enforcement is not effective in deterring illegal hunters from shooting protected birds,” continued Mr Barbara.

BirdLife has repeatedly asserted the need for Malta to institute a dedicated wildlife crime unit with the resources and specialist training needed if it is to effectively tackle illegal hunting and trapping. BirdLife Malta called on members of the public to continue reporting illegal hunting and injured birds incidents to the police and BirdLife.

Guidance on what is illegal and how to report incidents is available on the BirdLife Malta website, www.birdlifemalta.org.
