So that changes our idea about how these animals came to be,” said Rybczynski. they had the tail but didn’t use it,” said Rybczynski.Scientists had previously thought pinnipeds evolved from animals such as Enaliarctos, which lived along thewestern coast of North America and had gradually moved into the ocean.”The idea hasn’t been that there was this phase where they were living on the continent in streams and lakes. For some reason the pinniped lineage didn’t do that, and now we know they had had the option … Unusually, it is about 65 percent complete.Puijila was a carnivorous mammal with large canine teeth, a short snout and a powerful jaw. It had an elongated streamlined body, webbed feet and a tail that enabled it to move through the water at speed.The team — which hopes to return to the Arctic this year to continue the investigation — is particularly interested in why and how the Puijila came to lose its long tail.”Other mammals that went from land to sea, like whales and manatees, retained and made good use of their tails, (which) became propulsive structures.

We know they came from land mammals,” said Natalia Rybczynski of the Canadian Museum of Nature.”Our animal fills that transitional gap between the land form and the marine flippered form we’re familiar with today,” she told Reuters in an interview.Details of the expedition will be published in the latest edition of Nature magazine.The team found the fossil in 2007 during an expedition on Devon Island in the Canadian Arctic territory of Nunavut. ScienceThe very primitive animal, measuring around 110 cm (43 inches) from nose to tail, had a body similar to that of an otter, with a skull more closely related to a seal.It lived in and around fresh water lakes about 20 million to 24 million years ago.The mammal, named Puijila darwin, could move easily on both land and water and is a member of the pinniped family, which groups seals, sea lions and walruses.The science team has dubbed it “a walking seal”, although it is not the direct ancestor of any modern seal.The most primitive pinniped previously discovered was Enaliarctos, an animal that lived around the same time but was already fully flippered and had a streamlined marine body.”It (Enaliarctos) doesn’t tell us anything about how that lineage came to be. OTTAWA (Reuters) – Scientists in Canada’s Arctic have discovered the fossil of a previously unknown web-footed carnivore that helps explain how seals developed from land-based mammals, a member of the team said on Wednesday. Porker of the Month is a dubious honor given to lawmakers,government officials, and political candidates who have shown a blatantdisregard for the interests of taxpayers CAGWLeslie Paige, 202-467-5300 Copyright Business Wire 2009. For their record-breaking race to drink the congressional earmarking Kool-Aidand throwing their earmark reform pledges overboard, Reps Hunter, Jenkins andLance are CAGW`s April Porkers of Month. Citizens Against Government Waste is the nation’s largest nonpartisan, nonprofitorganization dedicated to eliminating waste, fraud, abuse, and mismanagement ingovernment. “They have joined thepolitics-as-usual crowd by talking like fiscal conservatives on the campaigntrail, but spending like Washington insiders once they`re safely in office.”Copies of the members` signed pledges are available to members of the media.

Jenkinsrequested $2 million for the Children`s Discovery Center and $834,500 forrestoration at Constitution Hall in Topeka; and Rep. Lance requested $896,400for downtown streetscape lighting upgrade to energy efficient lighting in thetownship of Cranford; $350,000 for the hike and bike path in BedminsterTownship; and $225,000 for the Hunterdon Family Dental Center “These three have broken their word,” Schatz continued. Hunter requested $2million for the Shoal Creek Pedestrian Bridge in San Diego, noting that”completion of the bridge will conclude an effort that has been ongoing over 10years supported by the local community and elected officials,” as well as$250,000 for the Boys and Girls Club Teen Center in Santee; Rep. The earmark requests are listed on the members` websites, as required byrecently passed earmark reforms Among the requested items violating the earmark pledge: Rep. Specifically, the three pledged “not to request any earmarked funding ortargeted tax benefit that does not serve a federal interest and/or have afederal nexus.” Contrary to this pledge, all three requested multiple earmarksin the FY 2010 appropriations bills that violated that plank of the ten-pointpledge. “Every year members of Congress betray the taxpayers` trust by bloating thebudget with earmarks, but this betrayal is particularly acute because thesethree representatives broke their signed campaign pledges just a few monthsafter being sworn into the 111th Congress,” said CAGW President Tom Schatz.
