Searching through some matrix I found this partial vertebra. Wish it was a bit more complete but maybe next one. This was found in marine sediment from near Richmond in Central Queensland Australia. It is from the Toolebuc formation witch is Cretaceous Albian about 98 - 100 million years old The longest length dimension is 6.5 millimetres so the animal it comes from must have been huge Also interested in where on spine this would have been situated if sufficient information can be gleaned for this partial. Thanks in advance for all input. Mike

Weird question i know, but i found this large coprolite from a Cretaceous inland sea site near Richmond in QLD, Australia and it is by far the largest single coprolite i have collected. As you can see it is almost the size of my hand, though if whole it would have actually been even bigger as there is a clear break on one edge where it would have continued further. The sea at this time was inhabited by a range of marine reptiles (7m ichthyosaurs, 10m long necked elasmosaurs and 10m short necked pliosaurs) but also by some pretty big fish, the largest of which was the ichthyodectid Cooyoo australis (a relative of the more famous Xiphactinus audux). This species could grow to about 2.5 - 3m long. There isn't really a sure way of knowing what produced this coprolite, but i was hoping maybe i could rule out fish simply based on the large size. Assuming a maximum sized Cooyoo, would a 3 metre fish be able to produce a poo of this size? Or can i safely assume it belongs to one of the larger marine reptiles? This is probably a question best aimed at collectors of the Smoky Hill Chalk as they may be familiar with the size of large fish coprolites such as those of Xiphactinus. @KansasFossilHunter @Xiphactinus Interestingly there is a small belemnite poking out of the coprolite on one side, so whatever it came from must have been eating belemnites. I'm thinking ichthyosaur is most likely.

While sieving through some matrix I came across this unusual tooth The tooth is from the cretaceous, albian, marine matrix from the toolebuc formation in central Queensland Australia. at 10 mm long it is not very big but there are striations on both flat sides, making it unusual compared to the normal fish teeth that are abundant. The edge on one side appears to be slightly rounded and the other that is chipped is quite acute. Thankful for any leads Mike D'Arcy

Finally got out for a bit of a fossicking trip to Richmond in central Queensland, did not bring much back home but overall a good trip. I went out to get more matrix from the hole where I have found some Mesozoic bird fossils and drop off to the museum the couple of fragments found while sieving through last trips matrix. http://www.abc.net.au/news/2017-04-19/dinosaur-bird-found-in-outback-queensland/8453740?pfmredir=sm Saturday 22 April 2017 - Day 1: Drove 5 hours out to Richmond and after a quick lunch went out to the quarry and went to the spot where I had found 30 odd Ichthyosaur on the last day of my trip earlier in the year to dig deep into to wall of the quarry, but as it is a working quarry much had changed and no luck there so I spent the rest of the afternoon specking and found one nice sharks tooth and half a baby ichthyosaur vert from I spot I had worked over a couple of years back. Yes I already had the other half at home. Early day so back to the pub and watch my team play football. Sunday Day 2: At the quarry by 7:00 and I started to dig down the 300 mm (1 foot) in the spot where the bird fossils came from and by 11:00 I had one bag of matrix in the back of the car and had the rest of the area where I wanted to dig down to the capping layer of rock over the matrix layer. I normally drive back to the caravan park to get out of the sun about this time but the local palaeontologist Patrick turned up and we got to chatting and having a general look around, so I did not go back for lunch until 1:00 pm. I then went for a visit to a local friend’s place for a chat so did not get back to the quarry until about 5:00 pm. I then dug out the other bag and half of matrix from my hole and left the quarry at dusk. I will see what I find in this lot of matrix before I decide where to dig next. Monday Day 3: At the quarry by 7:00 and thought I would have another look around where I had found the Ichthyosaur verts on the last trip but soon decided well and truly gone. I then decided to check along the wall of the quarry at the same level where I had picked up the verts on the last trip and noticed a Ichthyosaur rib in the side of the quarry face. After a quick dig around the rib to see if I could get it out I found more fossil bone so I excavated I bit more and decided there would be too much material for me to dig out and to material looked quite promising to having a fair bit of the skull there even if it was disarticulated, so I gave it a quick cover up and left. I then went back to Richmond to get the palaeontologist from the museum to have a look. I got him at about 8:15 on his way to work and once the museum was open Patrick came out to the quarry. We exposed a bit more of the fossil material and decided there was the potential to be a fair amount of the Ichthyosaur there based on the way the skull elements were facing. As I already knew, we also decided it needed to come out as a full dig and would need a backhoe to dig down to the layer where the fossil was as well as needing several people to lift the sections out and transport back to the museum for preparing. I was a funny feeling recovering the fossil that I had just found. We then pegged out the area and marked it with a Kronosaurus Dig Site sign, to be properly fenced of later. By 11:00 we got back to the Museum and looked a some of the bird material that I and some others had found next to the hole so are associated material. What I will say is with every bit someone finds of the bird material the better picture of what the association is with other Mesozoic birds found across the globe. After a break for lunch I went back to the quarry and did a bit more specking and talking to others out at the quarry. I picked up a turtle jaw in a piece of rock but not much else and left the quarry at dusk. Tuesday Day 4: Up early and on the road home by 6:30 for the five hour drive home and unpack the ute ready to go to work on Wednesday. Mike D'Arcy

Here is another shark tooth that I have no clue about. Found in Australian, Albian cretaceous deposit in the toolebuc formation near Richmond Queensland. tooth is just under 7 mm long thanks in advance for any input Mike D

I have finally started to sort through some of my small shark teeth and this one is a little different. As best as I can guess this is a johnlongia sp tooth. the photo with scale is in half millimetres so specimen is about 6 mm long. Thanks in advance. Mike D
