Found: Baker County, Montana 9.5 cm Label says Tyrannosaurus but with a question mark. So, is it Tyrannosaur, or even Theropod? So many of these bone pieces labelled tyrannosaur actually turn out to be Edmontosaurus. I am guessing narrowing it down to T-Rex would be very unlikely and difficult? Thanks for the help.

Partial right shoulder blade of a Spinosaurid. Very similar to that of the neotype skeletal reconstruction of Spinosaurus aegyptiacus. There are several large gnaw marks on the lateral side of the bone.

In Synapses vs Saurapsids, Synapsids get more diverse forelimbs. https://m.phys.org/news/2019-03-mammals-unique-arms-evolving-dinosaurs.html -
Is this an anomalocaris appendage? It was labeled as resembling an anomalocaris appendage, but Ive never seen one that looked like this, and I feel like Ive seen something else similar to this before. *wheeler shale, Utah.

I found this rather interesting piece on our favourite auction site. It's being sold as a croc vertebra. But it looks a lot like the ulna of an Abelisaurid from the Kem Kem beds. The resemblance with the ulna of Majungasaurus is pretty close. It's a little shorter, but the single bump on the one side seems to fit. While if it was a vertebra, it seems to lack a neural canal. Majungasaurus left ulna

I bought an articulated microscope arm a few years ago, but I was never really happy with it. The arm was too wobbly - the parts did not fit exactly and had too much play. While preparing I had to avoid bumping into the microscope, otherwise the microscope started to swing up and down. Now I have built myself a very sturdy double arm boom stand. I used two 16mm ball-type linear bearings and two solid linear motion shafts (16mm diameter, 80cm long). The end pieces and the support are made of aluminium - I had the holes drilled by a local company for 15 dollars. Together, it cost me about $ 90. Works fine! You can buy double-arm boom stands for about $ 200, but the arms are too short for my purposes.

I was wondering if anyone knew of a place to buy t arm stands that didn't cost a small fortune for more than 5 and ones that are smaller for the likes of teeth. So far I have found one website that all links into itself and feels like an old Angelfire website which in being pricey also doesn't make me want to put my card details in. And again thanks as always for any suggestions Matt

Partial right humerus (upper arm) of an undiscribed Dromaeosaurid. The size is very similar to that of Bambiraptor. This animal was possibly just over a meter long.
