Tidgy's Dad Posted February 3, 2020 Share Posted February 3, 2020 A couple of photos from the Late Ordovician of the Lawrenceburg roadcut, Indiana. The short stubby pieces with round holes filled with white are actually nearly complete specimens of the bryozoan Arthrostylus curtus. 2 Life's Good! Tortoise Friend.

I have no idea what happened with those initial photos, they still showed up for me for about 24h after you noticed, and then disappeared. Hopefully they all stick around this time! 1 hour ago, dinosaur man said: Sorry @Omnomosaurus but Daspletosaurus torosus is not know from the Dinosaur Park Formation it’s another species of Daspletosaurus not yet described “Daspletosaurus sp.” Again sorry it was just bothering me I’ll blame it on a little OCD Don't worry, @dinosaur man, I'm sporadically keeping tabs on that identification. A 2019 paper, 'Reassessment of a juvenile Daspletosaurus from the Late Cretaceous of Alberta, Canada with implications for the identification of immature tyrannosaurids' , examining a juvenile Tyrannosaurid postorbital from the DPF, concluded that it likely came from D. Torosus. You might be interested to know that the paper has also reclassified a previously identified juvenile DPF Daspletosaurus skull as that of an Albertosaurine. It therefore appears that Tyrannosaurine and Albertosaurine Tyrannosaurids were present in the DPF, and are probably more easily distinguishable that previously thought. Since my pics in the thread are of an anterior tooth with super fine denticles, it would more than likely point to D. Torosus, going by the identification methods of Hendrickx et al. (2019). 1 Link to comment Share on other sites More sharing options...

Cheers mate much appreciated. Bobby Here's a New Mexico Ordovician for you. Tidgy's Dad has the good stuff. This specimen is about 3mm at the widest. Rhynchotrema Capax is suggested from local geology papers and the location found. 3 Link to comment Share on other sites More sharing options...

Monica Posted February 8, 2020 Share Posted February 8, 2020 Hey @Bobby Rico! Since we finally saw some sun today, there was a bit of natural light so I thought I'd take a fossil photo for your macro thread... Here is my spiny brachiopod Devonalosia wrightorum (about 1.5cm by 1.5cm) from the mid-Devonian of Hungry Hollow near Arkona, Ontario. I think @Tidgy's Dad might like to have a look 4 Link to comment Share on other sites More sharing options...

Quer Posted February 9, 2020 Share Posted February 9, 2020 Ambulacra and apical discs often provide clues in the ID of echinoderms, so I try to make good close-up pics. Those are from Late Campanian of SE Pyrenees: Mamelons and ambulacra of an Almucidaris falgarsensis (Lambert, 1933) Ambulacra of an Goniopygus royanus (d'Archiac, 1851) Phymosoma hexaporum (Lambert, 1927) The four gonopores of a Diplodetus sp. Gonopores and ambulacral plating of another Diplodetus sp. 4 Link to comment Share on other sites More sharing options...
