Good morning everyone

I hope you can help me with this small sample. They were found in a garbage layer in the Inca site of Panquilma (Late Intermediate Period (900-1400 AD) -  Late Horizon Period (1470-1530 AD) located in the Lurin Valley - Lima, Perú.
The preservation in this site is outstanding but it has been hard to define the taxon for these three species. 
Please if you have any idea, let me know as soon as possible
