Terrible Lizards

Dr Dave Hone and Iszi react to an old dinosaur movie from the seventees.

We recommend watching this as a video, available on our patreon (as well as on Spotify) so you can see what we are reacting to.

This dinosaur bite is taken from an old bonus episode for our patrons back in 2021 where we watched the full movie (it was free on YouTube back then) and did a commentary.

Did dinosaurs raise each other's young like modern cuckoos do? Dr Dave Hone and Iszi Lawrence discuss how we would know if brood parasitism existed millions of years ago.

Having recently caught up with the much-overlooked prosauropods (or at least, overlooked by us), and after many requests from our patrons on patreon, this month we turn our attention to the crocodiles!

Much like birds, major parts of the biology of these animals (living and extinct) are critical for understanding dinosaur biology, evolution and behaviour, so we shouldn't avoid them as much as we have on here. Happily, this month we are joined by croc-supremo Chris Brochu to talk about his career in crocodilian biology and his work on these animals.

On the way, we get into a deep discussion on identifying species and what this means for taxonomy and evolutionary studies. But we start with some work Chris did as a postdoc on a certain fossil that everyone listening will have heard of: Sue the T. rex!

Iszi and Dave briefly discuss the new Netflix series "Dinosaurs".

They analyse the accuracy of the trailer including the opening with Spinosaurus's hunting technique, neck musculature, and nostril placement, comparing it to real-world evidence and previous research.

Dinosaurs in the Arctic and Antarctic likely survived cold conditions by using similar strategies to extant species. The discovery of a new T. rex femur, nicknamed Goliath, potentially validates predictions about the maximum size of these dinosaurs. Or Does it?

We have talked plenty about dinosaurs in pop culture, including in movies, but this is hardly a modern phenomenon. Dinosaurs were getting into the mainstream almost as soon as they appeared on the scientific scene and have a rich history in novels, and short stories. This week we are joined by Richard Fallon, a historian specialising in science in literature and with a particular interest in prehistoric animals in this context. Richard and Dave recently wrote a book chapter on the odds parallels between Jurassic Park and Michael Crichton and the Lost World by Arthur Conan Doyle. Having won a prize for this ("Doylean Honors" from the ACD Society!) we though it a great time to sit down with Richard and talk about dinosaurs and other ancient reptiles in fiction and how this has changed over time.

Here's some of Richard's collective works:

A new Spinosaurus paper was released, revealing a Spinosaurus with a larger head crest. While the new material is exciting, the larger crest is not surprising given the species' known display features. The new locality in Niger, further inland than previous finds, suggests Spinosaurus may have followed rivers inland, similar to other water-affiliated animals.

A new paper confirms long-held beliefs about spinosaur evolution, including sexual selection, wading behaviour, and multiple evolutionary phases. The discovery of a new rhabdodontid skull, with clear ceratopsian characteristics, suggests that some previously identified rhabdodontids were actually early ceratopsians. This finding supports the idea that ceratopsians were present in Europe during the Cretaceous, filling a gap in the fossil record.

In this episode from 2022, we delve into an incident that occurred in a Lower Cretaceous tracksite in Utah. A digger driven by the Bureau of Land Management accidentally drove over dinosaur tracks, causing damage to the site. This incident sparked outrage as the BLM was accused of violating procedures that required the presence of a palaeontologist.

We then discuss pterosaur evolution, exploring the common ancestor of dinosaurs and pterosaurs. We also discuss the remarkable size of Quetzalcoatlus and Azhdarchids, shedding light on the evolutionary journey of these magnificent creatures and why they are so much bigger than birds.

Dinosaur Bites is taken from a live we did back in 2024.

We ask where are the Australian Dinosaurs?

What was the first ever Dinosaur?

Why are only small dinosaurs feathered? (or are they...)

We've barely mentioned African dinosaurs (apart from you-know-what) over the years and have repeatedly failed to give much love to the early sauropodomorphs either (the 'prosauropods'). Happily, this month we're getting a great two-for-one deal by speaking to Kimi Chapelle who tells us all about her work on the incredibly well-represented, but not actually that well-studied Massospondylus. This species is known from dozens of complete skeletons but has attracted surprisingly little attention in the scientific literature and Kimi has been working to correct that with a whole series of projects on this animal and its relatives. There's plenty to discuss and more to come on these overlooked dinosaurs, so headphones on and enjoy.
