To mark the occasion of this new sub forum for museums. I would like you show you some wonderful stuff in Teylers Museum in Haarlem, Netherlands. This is actually the oldest museum in the Netherlands and thus also has some really cool history attached to it and it's specimens. http://www.teylersmuseum.nl/en Besides fossils this museum also holds an art and science collection. The museum is just as beautiful as the specimens in it and a true time capsule. While it is quite a small museum, it's charm is worth the trip alone. Even the cabinets are pretty. It even has a few world firsts, such as Archaeopteryx and Mosasaurus. Now on to fossils! One of the most important specimens on display here is one of the Archaeopteryx specimens. This is actually the first Archaeopteryx as it was found before the feather and the London specimen were found. But for a long time it was labeled as a Pterodactylus. Only later was it found that it was in fact an Archaeopteryx. While very incomplete it is one of the larger animals of the genus (the third largest I think). the specimen consists of slab and counter slab. If you look close you can still see the vague impression of the flight feathers on the wings. It also very nicely shows the keratinous sheaths of the claws. Archaeopteryx lithographica Along with Archaeopteryx Teylers also has a very nice collection of the Jurassic of Solnhofen in Bavaria. They have a number of Rhamphorhynchus skeletons, lizards, fish, crustaceans and squids complete with tentacles and inksacs. Rhamphorhynchus Various fish Homocosaurus maximiliani Various critters

Here's a specimen I found last August on the Yorkshire Coast, near Whitby (UK) and have recently got prepared. I didn't prepare it myself, but sent it off and have just got it back. What do you think? The specimen is a Zugodactylites braunianus, and it is from the Upper Lias of North Yorkshire. It's about 185 MYA.

Here's a brief description of how I prepped the Yorkshire coast Palaeocoma milleri that won last month's invertebrate competition. It was found in the middle of the top face of large, hard sandstone boulder. The tide was coming in quite fast and I wasn't sure if it was extractable in time - but after a frantic hour of chiseling a channel around it it was ready to lift. Always a scary moment but the Estwing bolster did the job . The resulting block is 12" x 8" x 3". The curly arm on the left was loose and broken into four pieces - these were carefully packed and glued back on at home. The next step was to rough it out with an air pen and abrader to see how far the arms went. Sadly, none of the others were as complete as the exposed one but that's often the way with brittlestars... Also, the surface of the central area is slightly corroded by the acid from a decomposing thin layer of pyrite - a common problem from this formation. I also used some potassium hydroxide flakes which is why the matrix has turned red-brown along the top arms. Then more work with pen and KOH to expose the centre disc and bring out the arms: It was then soaked for a couple of days to remove KOH. After more penning and tidying with the air abrader, the pen marks were ground away and that's as far as I've taken it - there's certainly scope to do more but I'm leaving it for now.

Hi everybody. I came back with this specimen. My sister found it recently but I don´t Know What is this. We know is a bone, but we are not sure if this fragment is an Icthyosaurus bone or other. What do you think. ? From Lias sediments, sea enviroment.

Hello, I've just finished cleaning these two ammonites (I think they're the same) from the Lower Jurasic ("Lias") of Lincolnshire, England, and was wondering if someone could help me work out what they are please? Thanks! https://flic.kr/p/neZBmP https://flic.kr/p/neZMzC https://flic.kr/p/nwvPWj https://flic.kr/p/nuryi7

I recently got round to prepping a few ammonites from my collection - I collected them during the summer (August) at the Yorkshire Coast (UK), but have only just got round to prepping them. I thought I'd share them with you. I'm not an experienced prepper, so I was practising on these ammonites. I am pleased with how they turned out, although I still have a little bit of work to finish some of them off. If anyone else wants to share their Yorkshire ammonites that would be great; once we get a thread going I'll post some of my other specimens. All of these ammonites are from the Lias of the Yorkshire Coast, UK, and were prepped out of hard limestone nodules. I used the Chicago Pneumatic from start to finish on all of theses ammonites, and then I gave them a light coat of beeswax.

Quick prep video of a nodule from the Upper Lias of the Whitby area I did the other week if anybody is interested.... http://www.youtube.com/watch?v=FMN1J6O-NEM&list=TL9fjxRxte4kno0x5ZseozgaSIbp8eJv0q If you happen to read this Jonny, note how thick the pyritic wall of the nodule is and that is why you need a TT when working on this sort of stuff especially if you are trying to remove it.
