My kids found these teeth near the excavation site for our recent sewer line repair. I am not a scientist, but we are very curious what information we might be able to glean about them. In my humble assessment, I can see they are molars of an herbivore on the size range of deer or horse. Having been found in the city of St Paul, MN under a residential boulevard, we're guessing they came from a prior life of this land, which had been farmed, and previously, Native land. Any guesses as to species and age are welcome!
