The Pleistocene-Holocene distribution of Unique Crocodilians (Crocodilia) Worldwide
Joseph Fossil posted a topic in General Fossil Discussion
The Crocodilians (Crocodilia) are a resilient group of reptiles, with the order originating around the Late Cretaceous 95 million years ago and still very prevalent globally in many aquatic ecosystems. But it was not too long ago that this group was even more diverse. Though way more diverse between the Paleocene-Pilocene eras between 64-2 Million years ago, the Crocodylomorpha (mainly Crocodillians) were still fairly diverse during the Pleistocene-Early Holocene eras - more diverse than they are today. This lack of diversity today is mainly due to the climate change that occurred between the Pleistocene and Holocene and (Unfortunately) overexploitation by Humans. Human induced Climate change since the Industrial Revolution and direct overexploitation by people still plagues many crocodilians today. It is only because of global Conservation efforts that some of the most endangered crocodilians today have a fighting chance at survival. I've decided to make a quick list of the unique crocodilians of the Pleistocene-Early(to part late) Holocene which can hopefully demonstrate the diversity of these magnificent animals during this time. Let me know if I forgot any examples. Australia - Quinkana fortirostrum (Pliocene-Pleistocene) Possible Unnamed Quinkana sp. (Possibly Q.fortirostrum) (Queensland Museum Specimen QM F57032) (Note: Quinkana could have grown to between 10-20 feet in length) Paludirex vincenti (Pliocene-Pleistocene 5.3-0.012 years ago) (Note: Plaudirex species could grow up to 4 meters (13 feet) in length) Paludirex gracilis (Pliocene-Pleistocene 5.3-0.012 years ago) (Note: Plaudirex species could grow up to 4 meters (13 feet) in length) Gunggamarandu manunala (Pliocene-Pleistocene 5-2 Million years ago) (Note: Gunggamarandu manunala could have grown up to 7 meters (23 feet) in length) Japan - Toyotamaphimeia machikanensis (Pleistocene 0.8-0.1 years ago) (Note: Toyotamaphimeia machikanensis could have grown up to 7.7 meters (25 feet) in length) Taiwan - Unnamed Toyotamaphimeia sp. (Pleistocene 0.8-0.1 years ago) China - Hanyusuchus sinensis (Early-Late Holocene (up to the 1400s A.D. around 600 years ago)) (Note: Hanyusuchus sinensis could grow up to 6 meters (19 feet) in length) Africa - Euthecodon brumpti (Pilocene-Early Pleistocene 3.5-0.781 Thousand years ago) (Note: Euthecodon brumpti could grow up to 10 meters (33 feet) in length) Crocodylus thorbjarnarsoni (Pliocene to Pleistocene 5.3-1.8 Million years ago) (Note: Crocodylus thorbjarnarsoni could grow up to 7.6 meters (25 feet) in length) Crocodylus anthropophagus (Pleistocene 1.845-1.839 Million years ago) (Note: Crocodylus anthropophagus could grow up to 7.5 meters (25 feet) in length) Madagascar - Voay robustus (Late Pleistocene-Holocene 0.1-0.01 years ago) (Note: Voay robust could grow up to 5 meters (16.4 feet) in length) Thailand - Gavialis bengawanicus (Early-Middle Pleistocene) Indonesia - Gavialis bengawanicus (Early-Middle Pleistocene) New Caleodonia - Mekosuchus inexpectatus (Holocene 0.012-0.004 years ago) (Note: Mekosuchus species could grow up to 2 meters (6 feet) in length) Fiji - Volia athollandersoni (Late Pleistocene-Early Holocene) (Note: Volia athollandersoni could grow up to 3 meters (10 feet) in length) Vanuatu - Mekosuchus kalpokasi (Holocene 0.012-0.003 years ago) (Note: Mekosuchus species could grow up to 2 meters (6 feet) in length) New Guinea - Murua gharial (Ikanogavialis papuensis) (Late Pleistocene-Early Holocene) What do you guys think?-

Likely/possible specimens of Tyrannosauroidea from the Southern Hemisphere (Jurassic-Early Late Cretaceous)
Joseph Fossil posted a topic in General Fossil Discussion
As a freshmen in College, I did a little extra credit report for my geology class about a controversial topic - Tyrannosauroidea diversity in the Southern Hemisphere during the Jurassic-Early Late Cretaceous periods. I was quite surprised at the amount of specimens I found. This diversity likely was the result of an early spread of the early tyrannosaur group Pantyrannosauria into Africa, Eurasia, and North America during the Jurassic and diversified once the land connecting these continents spread out more. Most of these species lived during the Early Cretaceous, though one or two exceptions might have lasted into the Early Late Cretaceous. I've created a list of known of the species and specimens which I would like to share on the forum (let me if there are any examples I'm missing or should add): South America Santanaraptor (Romualdo Member of the Santana Formation) (Early Albian, Cretaceous period 112.6-109.0 million years ago) Specimen: MN 4802-V (partial skeleton) http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&collection_no=67712 Tyrannosauroidea indet.

Are these crocodile teeth? Found in Darwin, NT, Australia
-
Hi there everyone. I would really appreciate your skills/opinions about if my little ''treasure'' is actually a coprolite or not. I have always believed it to be, just because it looks like a poo with something in it to me. I have forgotten where i found it, but most likely it was in Newcastle, NSW, Australia. It is ovalish in shape and appears to have a ''skin' wrapped around some sort of internal content. As I know zero about fossils, your time and expertise is gratefully appreciated. Looking forward to hearing from someone with excitement and thanks. Photos hopefully attached! Many cheers, Kazza

Drone assisted meteorite recovery - My Question: Why not Drone assisted vertebrate fossil recovery?

I came across this one today and am stumped as to what it is. It comes from a Queensland beach, Australia in a location where I mostly only find crabs and shells. There really isn’t any information on the age of the rock that they come from. The best guess is from a paper written in the late 1800’s suggesting a date of around 10,000 years. Judging by the gradient of rock colour/type I suspect some are much older.

Had a good time with my club yesterday when down at Batesford Quarry and got a nice haul for a first time down there. Not to many larger shark teeth in the piles but there were millions of regular fossils (mostly spines) but always a welcome sight to behold either way

Can radioactive fossils damage other specimens?
Maniraptora posted a topic in General Fossil Discussion
I know next to nothing about radioactivity-- enough to know licking fossils is inadvisable, although I'll admit that wasn't terribly disappointing news. What I'm wondering is whether specimens not radioactive enough to endanger a person are capable of damaging other specimens. Is there a need to segregate displays here, or am I just confused about the mechanics of this? My specific reason for asking is that at the moment I'm planning for my current favorite mineral specimen (which I am babying forever), an almandine garnet from Broken Hill, New South Wales, Australia, to share a small shelf area with a tooth from the phosphate deposits in Oulad Abdoun Basin, Morocco and a few dinosaur bone pieces from the Hell Creek Formation of Montana (one from Dawson County) and Lance Creek Formation of Niobrara County, Wyoming. The shelf is not enclosed, by the way. Thanks for your help! -
Hi everyone! Im new here, I wil soon make an introduction.I have a question. I recently came accros one of these fossils here in the Netherlands from an old private collection. Can anyone tell me about the rarity of this fossil? From what ive gathered its a set of fossilized leptolepis fish from the Talbragrar fish beds in New South Whales, Australia. Its a fossil site thats been closed for a while now. Even well known geologists that I know personally were unable to correctly identify this piece, never have they even seen such a thing. My piece is 22cm long (8,5inch), it has 3 small fish on and what appears to be an aquatic plant, fully white. 1 of the fish is whole, measuring about 4cm (1.6inch). I read the rules and heard that appraisals are not meant to be done on here. Any help wil be greatly appreciated. With kind regards, Sonny

Hi Guys, Just turned 50 and decided to realise my child dream of being a paleontologist and fossil hunter. I heard there are some possibilities for fossil hunting around Geelong, Australia (limestone quarries) and along the Great Ocean Road. I'm a complete enthusiastic noob and would be grateful for any guidance, especially from the local members of the community.

Hi guys, Today I have questions about my 2 rocks. They were found somewhere between Coonamble NSW Australia and Darwin NT Australia only about 3400kms so gosh knows the geological information my thoughts are I most likely picked them up between either Mt ISA and Winton Queensland or Katherine and Darwin NT but it was about 12yrs ago so I really can't remember what came from where except 3 other "special" ones that I can't locate at the moment because obviously I put them "somewhere very safe" First rock is pale grey and contains heaps of little quartz type crystals I don't really know what else to say other than should I crack it open? Second rock is more interesting to me as it is a harder rock encased in a calcite type material with a couple of little crystals in both hard and softer rock, my question on this one is should I try to dig a little deeper through the calcite material and see what the harder rock actually looks like? Kind regards Tara

Hi ive planned to head down to the beach at Torquay in Australia I’m im just asking what would I be looking for I know the general shapes and such for fossils laying about or in sand but I’ve seen some videos of people going through slate and sand stone and finding fossils inside and since I’m in Australia I was wondering if there is a specific type of rock or formation to look for since different countries and beaches have different geological layouts and such Thanks

Hello! The other day I visited a museum here in Perth and noticed they sold fossils in the gift shop. I bought a fossil of an ammonite as a gift for my younger sister, who absolutely loves anything prehistoric. The store gave no information other than it was an ammonite, but having bought it here in Perth I suppose it might well be from Australia at the very least. I apologise for not having more a specific location. If necessary I could send them an email and ask, though from the conversation I had at the store it seemed like the gift store staff weren't particularly well-informed themselves unfortunately. They came "pre-sliced" but I'm not sure if the internal structure helps at all. I also took exact measurements, as instructed. I hope the photos are sharp and well-lit enough! Thank you in advance!
