This article (http://www.foxnews.com/science/2016/07/24/148-million-years-later-dinosaur-quarry-remains-cold-case.html) shows how around 50 specimens of Allosaurus have been discovered in the Cleveland-Lloyd Quarry among other types of Dinosaur. They mystery to them is how they are all concentrated in that area. One secular researcher suggests that they were all washed into the area.
So this seems like a logical conclusion – based on the evidence: “A single catastrophe is the easiest way to explain so many bones in one place like the Cleveland-Lloyd Quarry, and even some secular paleontologists admit that.” (https://answersingenesis.org/dinosaurs/when-did-dinosaurs-live/allosaurus-creationists-best-friend/)
