The history of Alligators in South Dakota


RAPID CITY, S.D. (KOTA) – Alligators in South Dakota. Of course, there aren’t any gators roaming around in a nearby lake.

However, alligators did once call the state home.

Believe it or not, alligators did roam the lands of what is now South Dakota millions of years ago.

Interim Director of Museum of Geology Darrin Pagnac says the earliest records of alligators in South Dakota come from the late Jurassic Period.

“Our earliest record here in the Black Hills is from about 150 million years ago from the Morrison Formation. Morrison Formation is where Dinosaur National Monument is. So, we get a lot of long neck dinosaurs and allosaurs and that sort of thing and crocodilians are very common,” says Pagnac.

Pagnac added that it is common to find alligator fossils from the late Cretaceous Period in the northwestern part of the state. He went on to say that although alligators survived the dinosaur extinction 66 million years ago, the reptiles would later go extinct in the lands of what is South Dakota today.

“About 38 to 35 million years ago, that’s probably about the time they went extinct. And their extinction coincides with uh drying and cooling trend that we see throughout South Dakota. We lost these tropical swamps and forests and things really changed to a more temperate kind of seasonal environment,” says Pagnac.

Reptile Gardens General Curator Terry Phillip says historically crocodilians have been one of the most successful groups of animals in the world and they have undergone very few changes in appearance in the last 200 million years.

“Anytime you have an animal that has a fossil record that goes back that far, with very few changes, size being the biggest change that you’re going to see. They just got a little smaller. But, when you see an animal that successful, it just shows the design concept was perfect to begin with,” says Phillip.

Since alligators have been non-existent in South Dakota for millions of years, Earl Brockelsby opened Reptile Gardens in 1937 as a way to reintroduce them to the state.

VIEWPOINT | South Dakotans deserve the full story


Families in South Dakota work hard. We sacrifice a lot and ask very little from the people who govern us. We expect honesty, careful budgeting, and leadership that puts our interests above politics.

In his recent budget address, our governor painted an incomplete picture. He celebrated good results but did not explain what and who made those results possible. South Dakotans deserve more than selective storytelling. We deserve the truth.

Rep. Dusty Johnson backs Senator Rounds push for investigation into mail service in South Dakota


RAPID CITY, S.D. (KOTA) -Congressman Dusty Johnson is backing Senator Mike Round’s push for an investigation in postal service delays in South Dakota.

Johnson took to social media saying Senator Mike Rounds was right to ask for an investigation into postal service delays in South Dakota. Rounds had previously sent a letter to the postal service’s inspector general asking for her to find the cause of mail delays in South Dakota. Rounds said in his letter he has heard from hundreds of constituents across South Dakota. Johnson opened up with KOTA Territory News about his support for the investigation.

“I think the postal service is a terrible disaster,” said Johnson.

Johnson noted that in the past the service did what he said was a pretty good job. Johnson says despite sending letters and making phone calls with the postal service, he has not gotten any answers.

“I have asked if I can come down to one of their facilities, get a tour so I can better understand what’s going on behind the walls. They have refused to even let me, a member of congress, come learn about how they conduct their business. And so, this appears to be an enterprise that A, is not improving, B, isn’t communicating why there, why there failing and C doesn’t even appear to be particularly interested in getting better,” explained Johnson.

Rounds has pointed to the problem as being that mail traveling across or into South Dakota taking indirect routes. Rounds previously took a meeting with the postmaster general however the senator appears not satisfied with the outcome.

Rounds wrote in part in his letter, “I expressed my concerns about this to the Postmaster General (PMG) Steiner who downplayed such issue existed in South Dakota.”

In a letter sent to Rounds in October, Postmaster General David Steiner said that fixing issues at central region plants in Chicago, St Louis and Kansas City will likely improve outcomes and that at the time it was something the USPS was actively working on. The postmaster general acknowledged poor performance for first class mail at the beginning of the year and mid-summer but noted that it has since improved. During the week ending September 19th for South Dakota’s postal district, about %93 percent of first-class mail was delivered on time and roughly %97 percent was delivered within one day of its expected arrival. The postmaster general said he wanted to focus on the %3 percent that’s not getting to its destination on time.

“It may be only a small percentage of the mail, but because we deliver hundreds of millions of pieces each day nationally, the raw number is large,” wrote Steiner.

Steiner emphasized that some mail in South Dakota has always left the state for processing before going to another part of the state. The postmaster general explained that some mail requires certain sorting equipment and therefor some mail travels to plants with the right equipment.

The postmaster general also maintained in his letter that mail going to and from the same area in South Dakota is not leaving the state.
