New genus of tiny, hornless deer that lived 32 million years ago discovered at Badlands National Park

Researchers have discovered a new genus of prehistoric deer that they believe existed some 32 million years ago in an area around what is now southwestern South Dakota. The deer would not have resembled anything like the ones that exist today, though. A study into a fossilized skull found at Badlands National Park, which eventually led to the novel findings, suggested that all of these deer were hornless and roughly the size of a modern household cat.

The study was carried out by a team of researchers from the national park, the American Museum of National History and California State Polytechnic University, and published recently in the Proceedings of the South Dakota Academy of Science, a journal. 

Mattison Shreero and Ed Welsh, both rangers at Badlands National Park, led the research effort. They named the newly-discovered deer santuccimeryx, or “Santucci’s ruminant,” after paleontologist Vincent Santucci, who helped shape the paleontology program at the park, the National Park Service said this week.

In a statement to the agency, Santucci said that he was “personally and professionally grateful to be associated with this important new fossil discovery,” particularly because it came from the place where he started his career as a National Park Service paleontologist almost four decades ago.

Santuccimeryx as a genus belongs to the Leptomerycidae family, which is extinct, and roamed parts of North America from about 41 million years ago to about 11 million years ago. That family are considered close relatives of mouse deer, whose appearance follows the name and which live in tropical forests in western Africa and southeastern Asia, according to the National Park Service. But certain features of this creature were unlike anything else — the skull, for one, had elements characteristic of different prehistoric animals that lived almost 10 million years apart. 

Researchers identified similarly unusual combinations when looking at dental features. That led them to identify the fossils as part of “a distinct species” within the previously unknown santuccimeryx genus.

“Genus” as a term refers to the group within which multiple species exist. For example, dogs, foxes, wolves and a number of other dog-like creatures all belong to the same genus, called canis, while humans belong to the genus Homo sapiens. 

The hornless deer fossil was discovered in 2016 at Badlands, which, like the creature itself, would be an unrecognizable landscape during the period when the deer actually lived. Geologists say the rock formations that eventually became Badlands began being deposited well before the santuccimeryx, but erosion processes that led to the park’s current appearance did not start happening until 500,000 years ago.

Man stopped at border crossing with dead woman in car’s passenger seat, Croatia police say

Croatian authorities arrested an Austrian national on suspicion of trying to smuggle a corpse, after he was stopped at a border crossing with a dead woman riding in his car’s passenger seat, police said Tuesday.

The 65-year-old man was stopped at the Gunja border crossing with Bosnia in late November after presenting travel documents for himself and another passenger, police told AFP in a statement.

The officers then became suspicious after noticing the female passenger “was not conscious and was not communicating.”

Police called a coroner to the scene, who established that the passenger was dead.

Authorities said the 83-year-old woman had died in Bosnia, and the driver had tried to take her body to back Austria to “avoid formalities related to the transport of deceased,” the statement added.

Police did not elaborate on the relationship between the two, but local media has described the man as the deceased’s legal guardian.

Police said the case had been formally handed over to the country’s prosecutors.

Drivers in the U.S. have also been found with corpses in their vehicles for a variety of different reasons. Last year, a man in Texas was arrested after a man’s body was found inside his car nearly 40 miles away from where police there believe he was hit by the car. 

In 2014, a Detroit-area man said he refused to stop and contact authorities after one of his passengers died during a drive to Michigan from Arizona because he feared being incarcerated if police investigated. Four years before that, police said a Southern California woman drove around for months with a homeless woman’s mummified body in her passenger seat.

Rex Heuermann, alleged Long Island serial killer, due in court as prosecutors promise major development

Rex Heuermann due in court as prosecutors are expected to unveil significant development in case


Rex Heuermann due in court as prosecutors are expected to unveil significant development in case

02:17

RIVERHEAD, N.Y. Accused Gilgo Beach serial killer Rex Heuermann is due back in court on Long Island Tuesday morning, and prosecutors are promising a major development in the case. 

The hearing is set to begin after 9:30 a.m. A press conference is expected at the Suffolk County DA’s office shortly after. We will bring that news conference to you live on CBS News New York

The judge has previously indicated he wanted to set a trial date at today’s hearing. 

Heuermann’s last court appearance was back in October. 

Heuermann accused of killing 6 women, so far

Heuermann, 61, has pleaded not guilty to murder charges in the deaths of six women between 1993 and 2011. The remains of 11 people were discovered around Gilgo Beach during that period, and investigators believe Heuermann may be linked to other killings. The Suffolk County DA has said there could be future indictments. 

Four of the victims had their bodies disposed of near Gilgo Beach. Two others were murdered as far back as 2003 and 1993. Each of them had been involved in sex work. 

Prosecutors allege Heuermann is linked to the murders through DNA, burner phone data, a description of his truck, internet searches and what they call a blueprint for how to get away with murder. 

Attorneys wrangle over DNA, volume of evidence

A key point of contention in the new DNA evidence is called SNP, which prosecutors say links the hairs of victims to Heuermann. The defense has called an outside lab’s methods of genetic testing unproven and “magic.” 

Another hurdle for prosecutors is the sheer volume of evidence. The DA says they’re struggling to keep up with the costs of processing the 120 terabytes of data and 400 electronic devices seized. 

Heuermann’s attorney says his client is looking forward to his day in court and will be pursuing a change of venue, claiming the jury pool in Suffolk has been “poisoned.” 

Heuermann remains in isolation in jail.

Osiel Cárdenas Guillén — notorious drug lord nicknamed “Friend Killer” — returned to Mexico after U.S. prison sentence

Notorious drug lord Osiel Cárdenas Guillén has been returned to Mexico after serving a U.S. sentence and was quickly re-arrested and sent to a maximum security prison to face Mexican charges. 

There had been nervousness about the impending return of Cárdenas Guillén, who once led the feared Gulf cartel in northeastern Mexico before he was arrested and extradited to the United States in 2007.

The U.S. Homeland Security Department confirmed in its social media accounts Monday that Cárdenas Guillén had been returned after serving 14 years in U.S. custody, most of his 25-year U.S. prison sentence. He is a Mexican citizen, so presumably he was deported.

“The successful removal of Osiel Cardenas, a notorious international fugitive, underscores our unwavering commitment to public safety and justice,” said Enforcement and Removal Operations Chicago Field Office Director Samuel Olson in a statement.

A Mexican federal official who was not authorized to be quoted by name said Cárdenas Guillén had immediately been taken into custody in Mexico on drug, organized crime and money-laundering charges.

The official said Cárdenas Guillén was being held at the country’s top maximum-security Altiplano prison just west of Mexico City.

Homeland Security Investigations posted photos of a paunchy, balding, bespectacled Cárdenas Guillén being escorted by two officers in helmets and flak vests, and the being walked over a border bridge.

The image contrasts with the drug lord’s fearsome reputation for violence in Mexico.

Nicknamed “El Mata Amigos” (“Friend Killer”), he recruited former Mexican special forces soldiers to form his personal guard. The former head of the Gulf cartel was known for his brutality. He created the most bloodthirsty gang of hitmen Mexico has ever known, the Zetas, which routinely slaughtered migrants and innocent people.

The 57-year-old native of the border city of Matamoros, Mexico, moved tons of cocaine and made millions of dollars through the Gulf cartel, based in the border cities of Reynosa and Matamoros.

After his arrest in the northeast border state of Tamaulipas, he was extradited in 2007 to the United States, where he was sentenced in 2010 to 25 years in prison and ordered to pay $50 million.

At that time, the Justice Department alleged that Cardenas Guillen threatened to kill a Texas sheriff’s deputy who was working as an undercover ICE agent because he refused to deliver almost 1,000 kilograms of marijuana.
