After having another look at one of my bone fragments from the Bouldnor Formation (Isle of Wight, UK), the closest match i have been able to find is a bird acetabulum, as circled in the diagram below. But i am not an expert on avian anatomy. Can anyone else offer any insight? @Auspex Specimen is approx. 33 million years old. The Bouldnor Formation on the Isle of Wight produces a wide variety of mammals, turtles, crocodilians, birds, fish, lizards and amphibians. Measures 29 mm at its longest. The 'socket' which i think may be the acetabulum is 12.5mm in diameter.

Hi, I was hoping that you guys could confirm that this is a lepidotes dental plate (unfortunately minus the teeth). Found at Bouldnor on the Isle of Wight, UK. I’ve also added a photo of what I have hopefully correctly identified as a small piece of turtle shell. I didn’t find the shark teeth I was looking for, but these more than made up for it.

Last month my boyfriend and I went on our first ever trip to the Isle of Wight. We stayed for four full days and managed to squeeze in a fossil trip each day. On the first day we met up with one of my friends who was staying on the island with her boyfriend who is an 'islander'. We decided to visit the popular Compton Bay, an interesting and well known cretaceous site famous for dinosaur remains. When we arrived the tide was quite high and I didn't realise just how long it takes to go down (several hours, for future reference), but we were able to get onto the beach and walk a somewhat narrow strip of sand. After less than 10 minutes I picked up the first fossil! To me it looks like bone, but it has been loosely suggested to me it might be plant. It has a lot of iron rich matrix still attached to it which has unfortunately stained all my other fossils from this location as I desalinated them all in the same container (I would be glad to hear any advice for removing this staining?). Not 10 minutes after that I made the next find of the day, a small chunk of rolled bone. The tide was still very high so we decided to wander about the island and came back later that evening. Our lunch spot. The tide was lower in the evening and we had a wonderful time pointing out the dinosaur footprints, the trackway and finding pebbles full of shells, a pebbly full of bony fish bits and one more bit of bone for me and finally one for my friend as well (don't have pic of that though). Not sure how well the photos demonstrate this, but I think this may be a broken bit of a caudal vertebra. On day two we tried, and failed to get to Rocken End for some lovely ammonites. We couldn't find the right spot, so planned to try again the next day. In the afternoon we went to Bouldnor in search of some Oligocene turtles, crocodiles, mammals and whatever else we might find. However we were unlucky again and only found four chunks of Emys turtle shell. I am pleased with them though, as three of the four are really rather nice. It was a muddy but pleasant evening. Once again we had to wait a while (though 30 mins or so) for the tide to retreat. The first two pieces on the left were found within about 1m of each other. I'm not sure what to make of the 'stripe' on the top side of the third chunk. The next morning we found the correct access point and made our way to Rocken End, it's a fairly long walk down a steep hill(/mountain??) but wasn't as bad as it looked from the car park, there are steps carved into the mud at regular points. Soon enough we were scrambling over boulders of cretaceous upper greensand and pointing out ammonites that were poking out. Extracting the ammonites proved a significant challenge. They are incredibly delicate and soft. You could reach up and snap the ends out the rock very easily and practically all of the ammonites we attempted to extract came out in pieces, or broke irreperably. I did find two lovely little shark teeth sticking out, I believe these are somewhat uncommon here so I feel lucky. Just as we were leaving, my boyfriend found three ammonites practically lying on the ground in front him. They were by far the best ammonites we collected, he was very pleased with himself considering I had spent the previous two hours chiselling away whilst he sat and read his book... Prep in progress from the other side. The third one as found, just peeking out... ... and after some prep, it's still in the big block though, will (try to) cut a little pedestal out of the rock. Unfortunately the centre is missing. I also found a few beautiful brachiopods, bivalves and worm tubes - and also an echinoid! I have yet to ID any of these, but I think I actually prefer them over the ammonites, I wish I collected a few more.

Collected at Bouldnor on the Isle of Wight, and is about 33 million years old (Bouldnor Formation). This site produces a variety of mammals, turtles, crocodilians, birds, lizards, fish and amphibians. I am torn between labelling this a small caudal vertebra or phalanx. One end is unfortunately broken while the other is concave, with a rounded socket-like face to it. Measures 17mm long.

@TXV24 With two freshwater turtles known from the Hamstead Beds at Bouldnor on the Isle of Wight. The trionychid turtle Trionyx and the testudinoid turtle Emys as far as I’m aware. My best educated guess due to the location of the find and abundance of turtle material to be found with the right conditions at Bouldnor would be turtle. Are you familiar with turtle anatomy and recognise such a bone.
