Troodon Posted April 17, 2017 Share Posted April 17, 2017 Welcome to the forum. Can you tell us anything about it: -where it was found -do you know the age of the material it was found in an -what is its the size Can you clean up the matrix (material) on the specimen.

caldigger Posted April 17, 2017 Share Posted April 17, 2017 If you want some proper identification, please provide some information on location found, preferably age of deposition and something in your photo to show scale (how big it is). It really helps! Oops, Troodon beat me to it! Link to comment Share on other sites More sharing options...
Rockwood Posted April 17, 2017 Share Posted April 17, 2017 The problem here is that this look is common across a wide range of things in multiple kingdoms even. Link to comment Share on other sites More sharing options...
Peat Burns Posted April 17, 2017 Share Posted April 17, 2017 It looks like the OP has provided some very general location info in the tags: Neuquen Province, Argentina. Link to comment Share on other sites More sharing options...

Unfortunately the Neuquen Basin of Argentina is a near-continuous Late Triassic to Early Cenozoic deposit so we will need a closer target. Here is a photo from a travel site. 2 Link to comment Share on other sites More sharing options...

Troodon Posted April 18, 2017 Share Posted April 18, 2017 We are trying to determine the age to help you with identication but we are not familiar with the region and I do not understand the locality you provided . We don't know if we are looking at a dinosaur age fossil or one that is more recent. Can you mark on the attached map about were it was found. Can you also take a picture identical of the top one but the opposite side. Cleaning depends on how hard the material is. If it's very soft and soft tooth brush may work. If it's harder a tool like a dental pick or Xacto knife may work. Soften with acetone. Link to comment Share on other sites More sharing options...

Troodon Posted April 19, 2017 Share Posted April 19, 2017 I was hoping it was further southeast that is cretaceous but trying to determine age not going to be easy. Still would like to see more photos. map from paper https://www.researchgate.net/publication/223725121_Aptian_to_recent_compressional_deformation_foothills_of_the_Neuquen_Basin_Argentina Link to comment Share on other sites More sharing options...

abyssunder Posted April 19, 2017 Share Posted April 19, 2017 If you'll post some pictures, take also two shots straight from the ends, just to rule out (or not) other possibilities like coral or bryozoan.
