Hi everyone! I found a interesting rock with metallic luster here at home in Texas. I think it might be a mineral rock but I have know clue as to what type of mineral, Thankfully we have sites like this one for rookies like me that don’t have a clue about rocks and fossils. I have posted pics of the rock and would love to know what everyone else thinks about what mineral type it could be, thanks y’all!

Hello ya'll! It's been over 20 years since I picked up a pencil to draw anything until now. I'm a creative person by trade and avid fossil collector but don’t have a whole lot of knowledge about dinosaur anatomy? I always wanted to be a paleo artist to some degree, so here is my very first attempt to do a large scale drawing which is also a first of a T-rex! The reading glasses on the sketch will give you idea on scale. Go easy on me fellas, I've learned much from the challenge of this one and still have a ways to go! It may be my first but it won't be my last! When completed I will post it...just not sure when????

Hi all, I recently bought a dinosaur footprint, and it has a graphite outline. I was hoping it would just come off with an eraser, but it refuses to budge. I didn't want to just slap water on it and hope for the best. Is there a good way to remove the markings without damaging the footprint?? I'd love to display it natural. Thanks so much for any help!

Has anyone tried using graphite as a lubricant for air scribes?

Hi, Thought that I might share a little head study of Eotyrannus (T.Rex's great great great grandpa in terms of evolution) this is a small part of a lot of commissions that me and a professional paleontologist are collaborating and working on together as a team. We are especially fond of dinosaurs found on our home turf (the UK specifically the Isle Of Wight). So he wanted to see Eotyrannus recreated and this is the first illustration that I came too, there is a lack of Eotyrannus material, but I got the privilege of handling the real material that's kept safely under lock and key (thank god that I didn't drop it). (- Because there is so little of Eotyrannus found, some of this reconstruction is based on the Dilong which is a similar tyrannosaur that lived around the same time as Eotyrannus and they shared a few similarities in anatomy and possibly environment.) Anyway I hope that a few people like this little study I hope to upload more later on! - Beth
