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?
Oxytropidoceras posted a topic in Fossil News
If a person can find meteorites with drone, Why not vertebrate fossils? In the case of fossils, geological maps and aerial images take the roles of the radar and satellites used for meteorites.

Fossils sites in and around the Geelong area in Australia VIC
Calcium posted a topic in Fossil Hunting Trips
Hi I’ve been to some fossil sites over the year including: batesford quarry, Beaumaris fossil site and jan juc, but I’ve been trying to find more places online but unfortunately I haven’t been able to find any places on small forums etc mostly just the popular places most people know of. If anyone knows of any places that they are willing to share or talk about I’d be greatly appreciated and if you don’t want the place as public info I’m open to private messages -

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 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!

I have just researched what to look out for when hunting ammonites and other fossils and I read that they can be found in and around the Great Ocean Road but does anyone know any spots that had a high concentration of them?

Taxonomy from Lynne Bean 2021. Archaeomaene tenuis can be easily distinguished from the much more common Cavenderichthys talbragarensis by the more posterior dorsal fin. Diagnosis for Archaeomaene tenuis from Bean 2021 (modified from Woodward 1895): “ Same as family with the following additional characteristics. The supraorbital sensory canal has branched (ramified) tubules [*]. The dorsal fin is placed opposite to the anal fin. Pelvic, dorsal and anal fins are without fringing fulcra [*]. There are six uroneurals; the epaxial margin of the caudal fin has a few long basal fulcra and long fringing fulcra extending along the whole margin; both leading margins of the caudal fin have a single principal ray. Scales are elasmoid cycloidal [*]. (An asterisk [*] notes a uniquely derived character or autapomorphy of the genus).” Line drawing from Bean 2021, p. 116: References: Woodward, A.S., 1895.

Are these fossils? And if so, what of? Found under Seacliff Bridge in New South Wales
spagbutcher posted a topic in Fossil ID
Hi everyone! I'm new to fossil hunting and I found a few interesting rocks underneath Sea Cliff Bridge near Wollongong in Australia. There was a lot of coal in the area for context. I will attach some photos of the rocks I found, I'm particularly interested in the small white (quartz??) lines intersecting the black part of the stone. Any help would be hugely appreciated! Thanks

Dear Community, I need big help for small tooth that i found in North-east Queensland, Australia. I suspect it to be a shark tooth, but a missing root makes the search much harder.. I'll be using metric sizes, or specifically mm= millimeter Here the hard facts I can give: -ca 6mm long and 4,5mm wide -triangular shape, no serrations -no cusplets (maybe broken off?) Ps: sorry if I am spamming pictures, wasn't sure what lighting would be best... Thanks in advance for all the knowledge sharers and gatherers out there!
