A rebuttal in Astronomy & Geophysics countered that Loeb et al. had ignored that the amount of iridium deposited around the globe, 2.0 × 10 8 –2.8 × 10 8 kg (4.4 × 10 8 –6.2 × 10 8 lb), was too large for a comet of the size implied by the crater, and that they had overestimated likely comet impact rates.
The study confirmed previous findings that identified the asteroid as a carbonaceous-type, or C-type, asteroid, but refuted a 2021 hypothesis that the dinosaur killer was likely a comet.
The two-hour production hypothesizes the effects on modern-day earth of a large comet impacting in Mexico near the same location of the Cretaceous–Paleogene extinction event, the ancient impact of a comet or meteor that is believed to have triggered the mass extinction of the dinosaurs.
While the dinosaurs met their end around 66 million years ago in a catastrophic way, their extinction may have been crucial to the development of the human race.
A review in Systematic Biology complains that the book "at times seems a review of his and his colleagues' accomplishments" but nevertheless calls it overall "captivating".

Valley of the Dragons (UK title: Prehistoric Valley) is a black and white 1961 American science fiction film loosely based on Jules Verne's Off on a Comet and heavily dependent on stock footage from the movies One Million B.C., King Dinosaur, Cat-Women of the Moon and Rodan. [3]
Some deep sea creatures somehow managed to survive the asteroid impact that wiped out the dinosaurs 65 million years ago.
