I've been busy cutting some bases on a few fossils I've found and prepared over this year from Charmouth and Lyme Regis beaches. I'll be participating in the online Oxford mineral and fossil show this weekend. With photos, videos and my summer website update - both on here and on Facebook at around 12pm GMT on Saturday (18.07.2020). (Link in bio)
Lots of exhibitors are participating in the show - some doing live sales at selected timea. The page can be found on facebook, search for the 'Oxford Online Rock Show group' or DM me for a link.
I’m trying to organise lenses into groups for different jobs. This is the set I took with me hiking today (you can probably see by the sand). It was light but with a lot of options thanks to these kowa wide angle & telephoto lenses I got for £5, a variable ND and a closeup x4 filter that all fit into the MIr-1b. I also usually take either the industar or T43 with me as they are tiny. This all fit in my bum bag/fanny pack 😎 with enough space to pick up a bunch of random beach detritus! It wasn’t too heavy and it’s all stuff I don’t have to be tooooo precious about as i got it all for cheap - everything in the first pic probably cost under £70. When everything opens up I want to carry my camera all the time instead of my phone. #vintagelenses#travellinglight#bumbag#fannypack#mir#mir1b#industar#sovietlenses#kowalenses#kowa#telephoto#wideangle#diopters#variablend#fossils#hiking#whitecliffsofdover#industar50
Crinoids are marine animals, even though they look like plants, have lived on Earth for many millions of years. This incredibly intact fossil dates back to about 345 million ears ago. The earliest known unequivocal crinoid groups date back to the Ordovician, 480 million years ago.

💥A mammoth is any species of the extinct elephantid genus Mammuthus, one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair.
Hey guys. It’s me. Ya girl. ASDFGirl, dev and social media manager extraordinaire. You probably noticed all the radio silence on our accounts over the past few months. Not to worry! The mod is still alive, the devs are still alive. With everything going on in the world (i.e. coronavirus and protests against police brutality) social media was really stressing me out. Combine that with the stresses of interacting with mod fans on several different social media platforms, and it got to the point where I was feeling physically sick from it all. The new research on Spinosaurus was the last straw - so many people asking/expecting/demanding all of a sudden forced me to take an extended break. We’ll deal with Spinosaurus eventually, but it’s low priority since we have so much other stuff going on and that S.O.B. changes every other day. I’m back for the time being, but won’t be fielding questions about that demon dinosaur. Take it easy on me, okay?
This famous "Fighting Dinosaurs" specimen discovered embedded in the white sandstone cliffs of the southern Gobi Desert by a Polish-Mongolian expeditions team in 1971, preserves a Velociraptor in the midst of battle against a lone Protoceratops. Apparently locked in combat, these two fighting dinosaurs were remarkably preserved in this action pose for 74 million years. One possibility is that a sand dune collapsed on them while they were still fighting. This specimen is considered a national treasure of Mongolia.
Spesimen "Fighting Dinosaurs" yang terkenal ini ditemukan tertanam di tebing batu pasir putih di Gurun Gobi selatan oleh tim ekspedisi Polandia-Mongolia pada tahun 1971, mengawetkan Velociraptor di tengah pertarungan melawan seekor Protoceratops. Terkunci dalam pertarungan, kedua dinosaurus yang bertarung ini terawetkan dalam pose ini selama 74 juta tahun. Satu kemungkinan adalah bahwa gundukan pasir yang longsor menimpa mereka saat mereka masih bertarung. Spesimen ini dianggap sebagai harta nasional Mongolia.

The gold of the north 🌟 Baltic amber (34-48 million years old) caught by a fishing boat in the Danish North Sea 🧡🌊 More than 200 different color shades of Baltic amber have been registered 🌈😍
Published earlier this week, an extensive monograph describing new Dilophosaurus specimens reshapes what we thought we knew about the crested dinosaur.
These specimens include bones not known from earlier specimens, such as the braincase and pelvis, and the research has helped overturn some older assumptions. Dilophosaurus was once thought to have a weak bite force, but this new monograph reveals a much greater bite force than previously realised. Additionally, the distinctive notch between the premaxilla and the maxilla appears to have been less pronounced: the previous specimen was distorted post-mortem.
Our understanding of Dilophosaurus’ crest was also turned on its head, as it was pneumaticised like a modern hornbill’s or cassowary. This makes them stronger and lighter than we thought. Additionally, it was concave in shape, and were much bigger, stretching from the snout to behind the eye. Due to this structure, it has been hypothesised that the crests were the bony innards of a larger structure, perhaps fusing into one large crest, or even that the animal had an air sac for display like a modern frigate bird. We still don’t have a complete crest, so further discoveries will only increase our knowledge of Dilophosaurus’ life appearance.
The study also concludes that the group Dilophosauridae is not monophyletic, rendering it pretty much useless taxonomically. This is due to head crests being a poor method of distinguishing different groups.

Here's the holotype of #Nanotyrannus in its archival cradle! The skull was found in Montana in 1942 and is 572 mm in length. @gocmnh The second pic is my largest Nanotyrannus tooth. The serrations and enamel on the tooth are incredible. It looks like it has just fallen out fresh from the mouth.😂
