"I was at my sister in-law's house in Matteson, Illinois on June 25, 2011 at approximately 6:30 p.m.," writes Dale, "and we were in the backyard when I saw a large 'bird' flying through the air, kind of slow.
"It caught my attention even more because I noticed that on the back of the bird was a very long, skinny tail with a diamond-shaped tip. Then I noticed it had a very pointy face and his wings were bent inward and each wing had a long point sticking out from it. I couldn't tell if the color of the bird was black or gray.
"It was flying low enough for me to see a really good view of it. I was in shock, so I couldn't get my camera phone out, plus I didn't want to let it out of my sight. This was so amazing to me, and I can't get it out of my head."
What Dale is describing sounds like a pterosaur (see illustration above), which are thought to have died out tens of millions of years ago. Yet there are modern-day reported sightings occasionally.
It is unlikely that Dale saw a living dinosaur flying over his sister-in-law's house. Sometimes frigatebirds are mistaken for these long-extinct creatures. However, without a photo or video, we can neither confirm nor debunk the sighting. One interesting theory suggests that sightings of living dinosaurs are actually the ghosts of dinosaurs!
