Jaimin013 Posted December 10, 2023 Share Posted December 10, 2023 (edited) Diprotodon optatum upper incisor tooth Reddestone Creek (Pleistocene) Glen Innes New South Wales, Australia This fossil has recent export permissions from the Australian government. Super excited to be able to have the opportunity to acquire a fossil like this. For anyone who isn't familiar with Diprotodon it is the largest marsupial known & the last of the extinct, herbivorous diprotodontids. It was the first fossil mammal named from Australia (Owen 1838) & one of the most well-known of the megafauna. It was widespread across Australia when the first indigenous people arrived, co-existing with them for thousands of years before becoming extinct around 25,000 yrs ago. Received these incredible Australia dollar dinosaur collection coins with it too! Edited December 10, 2023 by Jaimin013 5 Link to comment Share on other sites More sharing options...

Danielb Posted December 12, 2023 Share Posted December 12, 2023 (edited) -Paramylodon harlani -Florida -Pleistocene I got this labeled as a horse tooth and I immediately knew it was a giant sloth Paramylodon tooth.

Psittacosaur9 Posted December 14, 2023 Share Posted December 14, 2023 Just received some lovely new fossils from the postbox today! Very hot in Australia currently but it was worth the trip to the post office for these! Strelley Pool Stromatolite from the Archaean aged Strelley Pool Formation, in the Pilbara in Western Australia. Funny that, seeing as the seller was American, this fossil travelled from Australia to a completely different country and then back again. Truly humbling to think that the life forms which resulted in this fossil lived 3.4 billion years ago. I've wanted true Precambrian material for a while (I also own a Dickinsonia replica), and I am far from disappointed with this beautiful specimen! Cretaceous, 95 million year old Onchopristis numidus rostral barb, from the Kem Kem Basin in Morocco. As some of you might know, I currently own a very badly prepared Onchopristis barb, and I got this one as a replacement. It looks awesome, and surprisingly it was cheaper than the other barb. This one's going straight into the display cabinet; I can still practise preparation techniques on the other barb, so it won't simply go to waste. 2 Link to comment Share on other sites More sharing options...

Kane Posted December 14, 2023 Share Posted December 14, 2023 Nice specimen. These commonly appear exfoliated and need the eyes reattached, so this was a good acquisition of such an iconic trilobite. 1 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

One of my favorites to collect. All sorts of teeth, seem challenging to find with complete side cusps. It is a shame, to find an otherwise nice tooth; that is missing a side cusp. 1 Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted December 19, 2023 Share Posted December 19, 2023 (edited) Time for a marine reptile update! These teeth came in for me over the past weeks... LTR: rooted Tylosaurus cf. proriger anterior tooth from the Ozan Formation; Temnodontosaurus platyodon rooted tooth from Charmouth; elasmosaur tooth from the Bissekty Formation of Uzbekistan and a goniopholid crocodile teeth from the same formation. Up first is a lovely and sizeable rooted tooth of Tylosaurus cf. proriger from the Ozan Formation of Texas. It's one of the few rooted US mosasaur teeth in my collection, and has a beautiful root structure. The crown has clearly marked tertiary striations and only a single mesial carina, the latter indicating this was an anterior tooth. Next up is a well-preserved matrix-free Temnodontosaurus platyodon rooted tooth from Charmouth, from the Obtusum Zone of the Lower Lias. Then there's this tooth crown of what appears to be a goniopholid crocodile from the Bissekty Formation that outcrops in the Kyzyl Kum desert of Uzbekistan and dating to the mid to late Turonian. Therefore probably Kansajsuchus borealis (see also here and here). From the same locality comes this partial plesiosauria indet. tooth. As it's ever so slightly subtrihedral and rather conical/uncompressed, yet has relatively weak striae, I'm still undecided whether this would be an anterior elasmosaur or polycotylid tooth. I haven't been able to track down much in terms of identification yet, though Wikipedia mentions the Bissekty-plesiosaur also occurring in a brackish water setting, which would rule out elasmosaur and favour polycotylid, seeing as the latter clade is the only one that, to my knowledge, is known to occur in brackish water. I'd therefore love to get me another one of these teeth, as this may help narrow down the clade, at least.

Hahaha! Yeah, always the usual suspects, right? 😅 I was initially pointed to check the page due to some other fossils of interest being sold.

Psittacosaur9 Posted December 20, 2023 Share Posted December 20, 2023 Just came in the mail today. Baltic amber with insect inclusions, aged 44 million years, found in Kaliningrad, Russia. Weird to think that, during that recent geological time, Russia was tropical. High definition photograph provided by he dealer of the insects. They are fungus gnats (Mycetophilidae) of an unidentified species. 6 Link to comment Share on other sites More sharing options...

I'm not sure exactly how far the tropics extended in the Eocene, but the planet was tropical enough for rainforests to extend to Greenland. The Palaeocene and Eocene were arguably just as tropical as the Mesozoic; in fact, during the Palaeocene-Eocene Thermal Maximun average temperatures were even higher than they ever were during the Mesozoic. 3 Link to comment Share on other sites More sharing options...
