In Depth The level of preservation in the holotype individual of Borealopelta is exceptional to say the least. Somehow this land dwelling dinosaur ended up in being preserved in marine sediment, possible suggesting that this individual may have been washed out to sea, perhaps in some sort of flood or land slide. It is probable … Read more
