Webinar: Dissecting Jurassic Park’s Dinos

The webinar, hosted by Nathaniel Janek and featuring paleontologist Ryan Huffed, begins with an introduction to the event titled 'Dissecting Jurassic Park's Dinosaurs.' The host explains the use of Q&A, polls, and the recording of the session. A poll reveals the audience's familiarity with the Jurassic Park movies, with 100% having seen the original. The host then passes the session to Ryan Huffed, who shares his background in paleontology and his current work with sloths. He also sets the stage for a discussion on the plausibility of the dinosaurs' existence as portrayed in the films.

Ryan Huffed outlines the meta premise of the webinar, imagining himself as a paleontologist responding to colleagues' claims of seeing real dinosaurs on Isla Sorna. He discusses the implausibility of obtaining dinosaur DNA from mosquitoes in amber, considering the geological time frames and locations of the amber deposits. Huffed also addresses the pronunciation of 'Parasaurolophus,' a dinosaur seen in the film, and conducts a live poll to gauge the audience's preferred pronunciation.

The discussion moves on to the inaccuracies in the portrayal of dinosaurs, such as the depiction of Parasaurolophus in water, which contradicts scientific understanding of their respiratory system. Huffed also highlights the mispronunciations of various dinosaur names and the geographical and time discrepancies in the dinosaurs' origins as depicted in the films. He emphasizes the importance of accurate scientific representation and the educational opportunities it presents.

Ryan Huffed delves into the scientific challenges of cloning dinosaurs from DNA found in mosquitoes, including the degradation of DNA over time. He points out that the closest living relatives to dinosaurs are birds, not frogs, which the film suggests as a source for填补 (filling in) DNA gaps. Huffed also discusses the size discrepancies of the dinosaurs portrayed in the film compared to their actual sizes based on fossil records and the implications of these inaccuracies.

Huffed addresses the presence of modern plants, such as grass and eucalyptus trees, in the Jurassic Park environment, which would not have existed during the time of the dinosaurs. He also discusses the concept of artificial aging of dinosaurs and the potential health implications. Furthermore, he touches on the issue of DNA half-life and the unlikelihood of obtaining usable DNA from mosquitoes in amber.

Ryan Huffed questions the use of frog DNA in the Jurassic Park narrative, given that frogs are not closely related to dinosaurs. He suggests that the choice of frog DNA indicates a lack of scientific accuracy in the film's portrayal of genetic engineering. Huffed also explores the possibility of creating new, biologically viable beings from unrelated DNA sequences, which would have significant ethical and ecological implications.

Huffed emphasizes the importance of scientists engaging with pop culture, arguing that it helps to humanize the scientific community and makes science more accessible. He discusses the representation of scientists in media and the need to be active participants in cultural conversations. Huffed also shares his personal experiences with science communication through his podcast, 'Science Sort of,' and his interactions on Twitter.

The discussion turns to the impact of carbon dioxide on the Mesozoic era, with Huffed explaining the role of CO2 in global temperatures and plant productivity. He suggests that the rise and diversification of dinosaurs were influenced by environmental factors, including CO2 levels, that affected the food chain and allowed for the evolution of various dinosaur species.

Huffed shares his thoughts on Pleistocene Park, a concept involving the reintroduction of large herbivores to the tundra to combat climate change. He differentiates this approach from the idea of cloning extinct animals, such as mammoths, expressing concerns about the ethical and practical implications of de-extinction efforts, especially when considering the status of modern endangered species.

The final paragraph focuses on the various ways scientists can engage with their communities, including judging science fairs, volunteering at schools, and utilizing social media platforms for science communication. Huffed encourages scientists to be proactive in outreach and to leverage their passion for science to inspire and educate the public.

In the concluding part of the webinar, Huffed shares his favorite scene from the Jurassic Park movie, highlighting the iconic T-Rex encounter during the storm. He praises the film's special effects and sound design, particularly the T-Rex's roar, which is a combination of alligator, tiger, lion, and baby elephant sounds. The host thanks everyone for participating and encourages continued discussion on social media or through personal contact.
