Looking for info on Temnodontosaurus eurycephalus
pachy-pleuro-whatnot-odon posted a topic in Questions & Answers
Probably one of the most enigmatic species of Temnodontosaurus is Temnodontosaurus eurycephalus, owing to only one skull ever having been found. This particular species is often described as a snub-nosed temnodontosaur with massive teeth and heavy jaw muscles that it probably used to hunt other ichthyosaurs (and other marine reptiles). Its holotype is currently held by the Natural History Museum in London, with the below being some images of it, taken off of Wikipedia: My interest with it, at present, lies with its dentition, with the morphology of its teeth. For I've seen some truly massive teeth and equally massive roots come out of Lyme Regis that I currently consider to belong to T. platyodon based on specimens labelled as such in the NHM collections (see images below for illustration, but please note that Ichthyosaurus platyodon is an old synonym for T. platyodon). And while these teeth seem morphologically similar to the teeth of Mary, Tony Gill's T. platyodon specimen (image below; source), I find myself wondering how these teeth compare to those of T. eurycephalus. Unfortunately, however, I've been able to find very little information or quality photographs on this particular species. I'd therefore like to ask if anybody here has any photographs - in particular crisp/detailed ones of the dentition - or articles (regrettably, I can't access pay-walled) that they'd be willing to share. Thanks in advance!

Hi all! I came across this tooth listed as temnodontosaurus. It's 4 cm long and comes from Lyme Regis. Can anyone here tell if it's temnodontosaurus? @pachy-pleuro-whatnot-odon

Following with the recent recognition of Mary Anning the Royal Mint has announced a commemorative coin collection in her name. https://www.bbc.com/news/uk-england-dorset-56182579 As part of the Royal Mint's "Tales of the Earth" series this follows dinosaur coins they minted last year. https://www.royalmint.com/our-coins/events/the-dinosauria-collection/ I find it really interesting how they're also tying in education on British paleontology and paleontologists. The new coins will also feature AR to discuss more about the specific fossils. A little fancy for me but I'm sure the educational information will accompany the Royal Mint website like they did in the Dinosauria Collection. Maybe some nice invertebrate fossils will appear on Tales of the Earth coins in the future.

My daughter is totally obsessed with Ichthyosaurs at the moment and top of her Christmas list is a paddle. I’ve seen full articulated paddles worth thousands so I’ve been trying my best to manage expectations. This popped up on an auction site a little closer to budget so after negotiating a little discount I have snapped it up. It’s from the Posidonia Shale of Holzmaden, Germany (Jurassic) and has been identified as Temnodontosaurus and while I have no reason to doubt this I’d welcome your thoughts on it. My main query is regarding the tooth that can be seen among the paddle bones. Does the size of the tooth match the size of the (partial) paddle? i.e. are they likely to be from the same animal? Alternatively, is it at all plausible that tooth belonged to another ichthyosaur that lost a tooth while biting off this section of paddle? Thank you for looking

New remains of a large Ichthyosaur from the Lower Jurassic of the Atacama Desert have been described. The fossils although fragmented, consist of dentary and rostrum remains and at least 11 teeth. The remains are assigned to Temnodontosaurus sp due to the similarities. It is the first marine macropredator in the Lower Jurassic of Northern Chile and the first example of the genus in the southern hemisphere Otero, R., Sepulveda, P. 2020 https://www.sciencedirect.com/science/article/pii/S089598111930519X#sec6-

Yesterday I was again in the quarry Kromer near Holzmaden (Lower Jurassic) and I found a really nice tooth ! The tooth is about 2 cm long and 1 cm wide ! I think its one of the biggest tooth I have ever found ! Its a Temnodontosaurus tooth, which is a large Ichthyosaur. In the "Schlacke" (a specific layer) you can sometimes find smaller teeth but such big teeth in a good condition are very rare. I am really happy about this one Especially because there wasnt much material there, so it was a lucky find ! The prep took about 4 hours. - The quarry, where I find this teeth will close during winter so the tooth is also a great completion of this year !

A very nice Temnodontosaurus tooth from the quarry Kromer near Holzmaden (Lower Jurassic). Temnodontosaurus was a huge Ichthyosaur. The tooth is about 2 cm long and 1 cm wide. So its one of my biggest tooth from Holzmaden ! In the "Schlacke" (a specific layer) you can sometimes find smaller teeth but such big teeth in a good condition are very rare. Some more pictures: -
Last week I visited the quarry Kromer near Holzmaden (Lower Jurassic) for about 4 hours and I found many cool things ! Beside of some belemnits I also found some nice teeth. Mainly they are very small but this time I found a nice one. Its a Temnodontosaurus tooth, a large Ichthyosaur, which mainly hunted ammonites. The teeth had robust roots so that they could withstand the stresses of cracking shells without breaking off. The tooth is about 2.1 cm long and I am very happy about this one. In the past I also found some nice Temnodontosaurus teeth but such teeth in a good condition are very rare. You will maybe wonder now about the negative title but as you can see at the pictures the tooth isnt perfect. A part of the root is missing and the surface is a bit damaged. Here are some impressions: Thanks for viewing !

From the album: Holzmaden
A beautiful and big (2.1 cm long) Temnodontosaurus tooth from the quarry Kromer in Holzmaden (Lower Jurassic). Temnodontosaurus is a very big Ichthyosaur, which mainly hunted ammonites. The teeth had robust roots so that they could withstand the stresses of cracking shells without breaking off. Such big teeth in a good condition are very rare in Holzmaden. Too bad that a part of the root is missing and that the surface is a bit damaged. Some more pictures: -
So I drew a paleo-reconstruction of a noteworthy but sparsely-known apex predator Temnodontosaurus eurycephalus, which was believed to be the top apex of the Early Jurassic until the rise of proto-pliosaurs like Rhomaelosaurus. Unlike its famous squid sucking sister T. platydon (metaphor, not literally), T. eurycephalus had a thick skull with deep jaws and large robust teeth suggesting a macropredatory diet and probably fed on other ichthyosaurs, plesiosaurs, and anything else that it could swallow (Also, growing lengths of over 30 feet, it probably could swallow everything other than another Temnodontosaurus) This is actually my first time finishing a paleo-reconstruction using only a pen tablet and photoshop (All my other drawings were either unfinished or done on paper). I used a Huion 1060PLUS drawing tablet and Photoshop CS6 to draw this. Took at least 3 hours to draw, and I heavily referenced the holotype skull to draw the head. Turned out pretty neat, but I don't know if I should color/shade this.
