RWA3006 You probably already showed this one but wanted to show it if you didn’t. Got this today from Randy with some other stuff. Thanks again Randy! I’m now the proud owner of my own pile of Dino dung!

Iron is fairly easy to detect by red or yellow colors. It would be interesting to know what else - and where - other elements are. www.google.com/search?client=firefox-b-1-d&q=spectroscopeswww.azooptics.com/Article.aspx?ArticleID=1382Atomic Spectroscopy Atomic spectroscopy was the first application of spectroscopy developed, and it can be split into atomic absorption, emission and fluorescence spectroscopy. Atoms of different elements have distinct spectra so atomic spectroscopy can quantify and identify a sample's composition. The main types of atomic spectroscopy include atomic absorption spectroscopy (AAS), atomic emission spectroscopy (AES) and atomic fluorescence spectroscopy (AFS). In AAS atoms absorb ultraviolet or visible light to transition to higher levels of energy. AAS quantifies the amount of absorption of ground state atoms in the gaseous state. AAS is commonly used in the detection of metals. In AES, atoms are excited from the heat of a flame, plasma, arc or spark to emit light. AES used the intensity of light emitted to determine the quantity of an element in a sample. Techniques that use AES include flame emission spectroscopy, inductively coupled plasma atomic emission spectroscopy, and spark or arc atomic emission spectroscopy. In AFS, it is a beam of light that excites the analytes, causing them to emit light. The fluorescence from a sample is then analyzed using a fluorometer, and it is commonly used to analyze organic compounds.

Fascinating thread, RWA3006, do you have an example of a coprolite from a carnivore? I am interested in seeing what differences there would be. Thanks!

Fascinating thread, RWA3006, do you have an example of a coprolite from a carnivore? I am interested in seeing what differences there would be. Thanks! I don't have any carnivore coprolites probably because the areas I search are so relatively rich in hadrosaur coprolites they seem to monopolize my attention. I imagine carnivore coprolites are present in those areas but they are not really on my radar while I'm hunting because I'm so focused on finding specimens with a specific morphology that my eye is tuned towards those almost exclusively. I often try to break out of having mental blinders but I so enjoy the hunting, searching and seeking that the pursuit consumes me to the point of exclusion of other significant things. Many southern Utah coprolites have exquisite agate replacement features that are not common in carnivore coprolites around the world so I have to confess that those without the brilliant agate patterns don't attract me because I'm heavily biased towards the agatized hadrosaur variety from Utah. I should not assume that any potential carnivore coprolites from the areas I frequent are lacking agatized features, so I will try to modify my searching mentality in the future. I am not aware of any agatized carnivore coprolites in existence, and it would really be something to find one.

We use our senses to connect to what we want and ignore most of the rest. In our agate quest we could walk over diamonds and never notice. Someone with gold fever will bypass all kinds of treasure.

This specimen shows the dark red jasper gastrolith granules that are so common in southern Utah coprolites. In fact, their presence is so prevalent that at times when I find a mysterious rock that is difficult to identify as coprolite I will use the presence or absence of these granules to help determine it's identity. I hypothesize that these distinctive sand grains were prominent components in the beach or alluvial gravels contemporary to the hadrosaurs.
