If you're interested in science you're familiar with Piltdown man, formally named Eoanthropus dawsoni in 1912 but shown to be hoaxed in 1953. What you may not be familiar with is the DUALIST CONTENTION, and here's a thread on it...
Yes, the one thing that every single person who’s heard of Piltdown man knows is that it was eventually determined to be a hoax. What’s discussed less frequently is that early 20th century views on Piltdown man were -far more complex- than popularly portrayed...
Acceptance of Eoanthropus as a valid proto-human (as per the Margaret Flinsch illustration here) might have been the 'mainstream' view that made it into textbooks and encyclopedias, but it certainly wasn’t the only one, nor was this acceptance wholesale or uncontroversial...
Piltdown man’s describer was Arthur Smith Woodward of the British Museum (Natural History). But Woodward was an ichthyologist, not a hominid or primate expert. In the UK, Woodward had some aggressive supporters who argued that his interpretation of Piltdown man was right. BUT...
Certain anthropologists, primatologists and mammalogists were of the opinion - as earlier as 1915 - that the partial cranium and jaw of Piltdown man did not go together, and that while the cranium was human, the jaw was from a chimpanzee or some other non-human ape...
Gerrit Smith Miller in Washington, DC argued in 1915 that the Piltdown remains didn't go together, and that a chimp jaw - if broken in the right place - was almost identical to the jaw of Piltdown man. Miller argued that the cranium was from a human, the jaw from a fossil chimp..
King’s College anatomist David Waterston had also argued for the incongruity of the remains in 1913. French palaeontologist Marcellin Boule and German anthropologist Franz Weidenreich in 1923 argued likewise, as did Aleš Hrdlička [shown here] in Washington in 1923/24. In fact...
Given the poor stratigraphic data from the Piltdown excavation, Hrdlička intimated that the Piltdown cranium might be a modern burial that had been incorporated into older strata (the picture shows the 1938 Piltdown man memorial, still in place at Barkham Manor, East Sussex)...
Hrdlička examined the Piltdown remains himself in 1922. By that time, the alleged 'Piltdown II' specimen (a tooth) had been found. It was so similar to the teeth of Piltdown I that he wondered if it had been mislabelled: could it actually be part of the Piltdown I remains?
In reality, it was a hoax, just like Piltdown I. Miller, Hrdlička and their colleagues - all expressing doubts about Piltdown man's identity and homogeneity during the 1910s and 20s - have been dubbed 'the dualists', since they thought that Piltdown man consisted of two animals..
In other words, red flags were present throughout the history of one of palaeontology’s greatest hoaxes, yet were ignored by workers who held influential positions. Here's John Cooke's 1915 'Piltdown gang' painting, today at Burlington House, the Geological Society of London...
Woodward and his colleagues in the UK, and Henry Fairfield Osborn in the US (Osborn became a Piltdown supporter in 1921) should have listened to Miller, Hrdlička and the others, and to the reasonable, well supported dualist arguments. Alarm bells were ringing from the start...
In 1967, the #DSRV#Alvin was attached by a #swordfish at a depth of c 600m. The swordfish charged the vessel at speed and got virtually the whole of its rostrum embedded in Alvin's hull. The fish survived ascent to the surface but was killed and eaten. Cont...
#Swordfish (and other billfishes) have often rammed large objects at speed - their broken rostra have been recovered from ship hulls, turtle shells and baleen whale heads. In 2016, one rammed a diver doing maintenance on a Brazilian oil platform and impaled his air tank...
A 2021 study by Patrick Jambura et al. described a case in which a dead Bigeye thresher shark was discovered with a partial #swordfish rostrum embedded in its gill region. You can read that study here... link.springer.com/article/10.100…

Goosebeak or Cuvier’s beaked #whale (#Ziphius cavirostris): described as a fossil in 1823 but realised in 1872 to be the same as beached specimens reported in 1820s but given different names. Ziphius is near-globally distributed (pics: specimens from Bay of Biscay; NOAA) 2/n
Bush dog (Speothos venaticus): named as a fossil in 1839 - which explains Speothos, meaning ‘cave wolf’ - and described alive 1843. The same person, Danish naturalist Peter Wilhelm Lund, described the fossil AND living animals, but ... 3/n (pics Attis; Bonne1978; CC BY-SA 3.0)
During the early 1990s, John Blashford-Snell, Rula Lenska and other travelled to Nepal to find and photograph the giant #elephants Raja Gaj and Kansha. They succeeded, and got great images of both animals. They later wrote a book about their adventures... 1/n
The twin-domed skulls and convex trunk bases of these animals - Raja Gaj in particular - led to suggestions (albeit only in talks and popular articles) that they were 'living mammoths' or 'living stegodonts'. I asked Blashford-Snell a few times where these ideas came from... 2/n
They were the result of confusion. The Nepalese giants had been compared by some elephant experts to Elephas hysudricus, an Asian #Pleistocene fossil #elephant with very prominent cranial doming. No deliberate reference to mammoths OR stegodonts! 3/n
I've just been looking at Big Sara, the privately owned #Allosaurus skeleton (genuine fossil, not a cast) currently on show at Westquay Shopping Centre, #Southampton. What a spectacular specimen! Here are some thoughts... #dinosaurs#fossils
I've heard some concerns about the displaying of this genuine fossil in a food court. I have no idea how the specimen is faring in terms of pyrite decay and so on but...
... it's not in an environment that will contribute to decay. Indoor spaces like this are, in the UK, not humid, but cool and airy. Big Sara is in a big open space close to a giant window. Moving to anatomy...
I was lead scientific consultant on #PrehistoricPlanet and was extensively involved in our many decisions, all of which were science-led or scientifically informed. I was, of course, merely one among many in a HUGE team that involved hundreds of very talented people!
Ep 5 focuses on the #dinosaurs and #pterosaurs that lived in forests during the Maastrichtian (the final part of the Late #Cretaceous). The Maastrichtian world was heavily forested, with temperate, subtropical & tropical woodland covering around 78% of the land surface…
