The Bozeman Police Department is proud to sponsor the tenth session of our popular Citizen’s Police Academy, beginning in just over a month.
This free class will meet every Wednesday evening from 6:30-9:30 pm for ten weeks, with an additional opportunity to ride along with a patrol officer. The academy starts March 22 and concludes on May 24, 2017.
One of the main objectives of the Citizen’s Police Academy is to foster stronger communication between the citizens of Bozeman and the police department. Another objective is to provide information about the department and criminal justice system so students have a better understanding of the services the Bozeman Police Department provides to our community.
Topics will include an overview of the department, patrol operations, the detective division, use of force issues, DUI and drug recognition, drug task force operations, the K9 unit, the special response team, dispatch center operations, and internet crimes functions.
If you are interested in attending this high-energy event or have questions, contact Community Resource Officer Mike Bachich at mbachich@bozeman.net or at 582-2969. You may also find the application on our website.

A Montana State University scientist was involved in a recent discovery of a 250-million-year-old fossil from China that has scientists rethinking how reproduction evolved in a group of animals that includes birds, crocodiles and turtles.

The fossil, called Dinocephalosaurus, is a long-necked, fish-eating marine reptile dating to the Middle Triassic period, and contains an embryo inside its abdomen. This unexpected evidence is the only known example of live birth in this large group of vertebrates known as Archosauromorpha.
“This is the first archosauromorph species known to have given live birth, meaning it didn’t lay eggs” said evolutionary biologist Chris Organ, an assistant research professor in the MSU Department of Earth Sciences in the College of Letters and Science. “The ancestors of Dinocephalosaurus lived on land — live birth was likely an adaptation that helped it reinvade the marine environment.”
The findings were published Feb. 14 in the scientific journal Nature Communications. Jun Liu from Hefei University of Technology in China, was lead author of the paper, “Live birth in an archosauromorph reptile,” which included Organ, as well as collaborators from England, Australia and the U.S.
The discovery will also be shared in the journals Nature, Science and Science News, among other outlets.
The specimen was found in three limestone blocks in a field in Luoping County, Yunnan, China.
“We were so excited when we first saw this specimen several years ago,” Liu said. “We first saw the blocks lying at the side of a field. We had to remove the soil and dig out the slabs to take them back to the lab for preparation.”
While the discovery shifts the understanding of how reproduction evolved in animals, Organ and his colleagues predicted as much in a 2009 paper published in the journal Nature, “Genotypic sex determination enabled adaptive radiations of extinct marine reptiles.”
“We predicted that if we found a new reptile fossil completely adapted to life in the ocean, it would also have given live birth and have had sex chromosomes,” Organ said.
Dinocephalosaurus sits on the evolutionary timeline between crocodiles and turtles, Organ said, and its ancestors lived on land.
“Like whales and dolphins, it evolved adaptations to live permanently in water without returning to land to lay eggs,” he said. “Whereas sea turtles are reproductively bound to land to lay their eggs, Dinocephalosaurus was free of this constraint by giving live birth, a trait that was likely preceded by the evolution of sex chromosomes.”
This past year, Organ was also one of three authors of a paper that linked bony cranial ornamentation to dinosaur body size. That paper, "Bony cranial ornamentation linked to rapid evolution of gigantic theropod dinosaurs,” was published in Nature Communications on Sept. 27.

Definitely not the quality it used to be. Mint cholate chip just has big chunks of chips stuck together not throughout the nearly mint flavored ice cream. Sorry you’ve lost me
