Not disputing it's Theropod just that I don't see anything diagnostic to tie it to a Carch and it might be.  Ornithomimids and Deltadromeus also have long tarsals have you considered them

 

No only Theropod s and Birds are hollow.   Can you determine if that bone is hollow all the way through.  I ask the question simply because hollow bones are thin and smooth on the inside?

If we are talking about the small femur looking bone it's incredibly light and gentle taping seems to indicate it's hollowness right the way through.

 

If I am reading this right Deltadromeus.JPG

As I don't have the larger version for this the metatarsils are between 20 and 25 cm and this is 38.5cm with a bit missing from both ends also has delta even been confirmed from this region I know sellers use it all the time as a label and as for ornitomimids I have no clue but have become aware of the possible presence from your Tuscan show information and the ugunal you have.

Can confirm the small femur looking bone is hollow to at least 3cm in without putting any pressure on it might be able to confirm it's entirely hollow with something long and thin enough.

FYI, we have accurate metatarsal III numbers on a few, Gualicho shinyae which has strong affinities to Deltadromeus is 31 cm,  

Aucasaurus is an Abelsaurid whose M III is 34.  These are complete bones and do not know if they are adult specimens.   With the possibility of there being an ornithomimid around it's Tarsal bones are typically very long.  

While yours may be a Carch without comparative specimens its hard to draw conclusions.

 

If your bone is hollow throughout it's definitely not reptilian

Forgot I had this bone but its an outside metatarsal that measures 37 cm.  It would probably fit your bone and I have a hard time assigning it to any theropod.

Ok thank you for all your help I have some more pieces I could use help identifying when I get back to England in the time being here are some nice photos taken from a very cold desert (the good thing with these is a can tell you exactly which layer they came from but later)

P.s.s. Also I had to crop last photo to exclude faces sorry about this.

This was one tooth that caught my eye does not have a significant (But has minimal) twist however. 9.3mm long 3 denticles per mm on distal 4.2 to 4.7 denticles on mesial

Nice photos, tooth could be Carch.

Serration shapes look carchy as well as tooth shape. The denticals look massive in relation to the tooth so maybe just the very tip?

Will need to look at that tooth closer. This is hollow but has a rather thick wall to it, I first thought tibia but leaning more toward another metatarsal length is 102mm and weight is 19g, applogise for not uploading more finds sooner had to go down to Bristol for a friends birthday, which was fun and got to go the aust cliffs and then ended up coming down with influenza so only just getting to the mystery pieces now.

Yes that looks to be a good match, can you help clarify what it means then for a theropod bone to be hollow? This might seem a basic question but its one that still confuses me rather a lot and never seem to be able to get any certain pictures of the limb bone cross sections (I am doing the dino course hosted by course-era btw) and again thanks troodon.

This is really helpfull but one small question what are the numbers (decimal percentage) representing in the graph from the journal article and also is that a free journal article or locked behind a paywall? also this is another one i have no clue to the only think i can think of is a comment someone made about sauropod vertebrae being heavily pneumatized but doesn't looks right even for a vert process one side completely flat.

@LordTrilobite I feel you are the expert on chuckosaurus from the kem kem :ighappy:

That's a tough one. I tend to see these types of structures in large mammal skulls. But I have yet to see them in a specific place in the body of a dinosaur. Yes many dinosaurs, like sauropods and theropods can have heavily pneumatisized bones, especially vertebrae. But so far as I know they tend to be large hollows without much interweaving struts as far as I know. Structures like these remind me more of skull material. But I have nothing to compare this to. So I really don't know.

 

The thing with chunkosaur stuff is that sometimes it's still possible to identify, that is, generally, if you have seen a more complete version of the same type of bone so that there's good reference.

The partial femur with the head missing is hollow through and has a smooth wall to the inside and fits the kem kem theropod thickness chart that was posted by troodon it's still sticks in my mind that this is very small for a femur and the walls of the bone are too thick for pterosaur. Did you mention @LordTrilobite you have a bone that fits a bambiraptor replica you where making maybe this would be something like this?

Do you mean this one?

This is also one of many interesting hollow bones I picked up.

No, I don't see much resemblance to the femur of Bambiraptor or other raptors.

 

This is the femur of Bambiraptor, it really doesn't match.

Ok I'm uploading some more images that have been correctly taken with a DSLR not a mobile phone, maybe this can help with the identification again the bone is hollow the way through, which i can back up with phone images if needed, any suggestions on what it might have came from would be great.IMG_0113.thumb.jpg.21088e107c683d7936c1199cdced6224.jpgIMG_0114.thumb.jpg.e1878884e831251452a5966bf94d3bf6.jpgIMG_0115.thumb.jpg.253a1038838fb3b21daa8749f0a1b992.jpgIMG_0116.thumb.jpg.c8f13205a0ced31cf475c5a3471a7394.jpgIMG_0117.thumb.jpg.869209826a83e8a6eae3ef4cde8eb275.jpgIMG_0118.thumb.jpg.f4b0ef3c54f95c2e6fa079ad113ac5c3.jpg

Well there's still not much new information here. It looks like a femur with the head at the hip missing. The knee is double headed, so that doesn't rule out dinosaurs. But towards the top it has that weird indent that I do not recognise. Until a good match comes along I'd say it's an indeterminate femur.
