Nathan and his father sent photos of the partially exposed bones to the Royal Tyrrell Museum in Drumheller, which confirmed that the bones came from a young hadrosaur, otherwise known as a duck-billed dinosaur.
A 12-year-old boy has discovered a dinosaur skeleton dating back around 69 million years in what paleontologists have described as an important find.
The report said, the skeleton's excavation was completed this week.
"This is very significant for the Nature Conservancy of Canada because when we talk about land conservation we talk often about the benefit for future generations but this is a really good opportunity to point out how conserving important landscapes also help us unearth mysteries of our planet's history", said Carys Richards the communications manager with the Nature Conservancy of Canada.
"I was in so much shock", he told CBC Kids News.
"I've always just been so fascinated with how their bones go from bones like ours, to solid rock". Fossil discoveries are rare in this geological layer.
Nathan and his dad travel to Drumheller from their home in Calgary every summer to hunt for dinosaur bones.
Nathan and his dad, Dion, had found bone fragments in the area on a previous hike and thought that they might have washed down from farther up the hill.
"He called down to me, he's like, 'Dad, you need to get up here, ' and as soon as he said that I could tell by the tone in his voice that he found something", Dion Hrushkin said.

"Now, the blocks are going to be rolled into our preparation lab, which visitors to the museum can look through the window and see all the technicians slaving away at opening the big blocks covered with burlap and plaster and then using a variety of small tools to carve out all the rocks and expose the bones very slowly".
"It looked like the end of a femur - it had that classic bone look to it - sticking straight out of the ground".
According to the BBC report, the museum sent a team of experts to excavate, because although many fossils can be found in the Badlands - and a dinosaur named the Albertosaurus was discovered there in the late 1800s by Joseph Tyrell - the part of the conservation site where the Hrushkins were walking was not known for fossil discoveries.
Nathan said the experience has motivated him even more to pursue his dream. They took photos of the fossils, noted the coordinations to their location and how they got to the spot, and emailed the museum.
"It represents a gap about 69 million years ago, when we don't know what type of dinosaurs lived around here", Therrien said.
The NCC says that all of the bones collected belong to a single specimen, a juvenile hadrosaur approximately three or four years old.
Most importantly, the Hruskins did not touch or disturb the fossils.
"But after my discovery, it's most definitely the Hadrosaur".
"What's interesting about this find is that it comes from a time interval for which we know very little about what dinosaur species lived in Western North America during that time period".
"The discovery of Nathan and his father will help us bridge this big gap in our knowledge about the evolution of dinosaurs", said Francois Terrian, Secretary General of the Museum's Ancient Environment, in a statement.
Nathan says he's enjoyed learning more about dating dinosaur bones, and that the whole process has been "surreal".
