Measurements of the coprolites, number of elytra in each coprolite and descriptions of other inclusions. The diameter refers to the maximum diameter. Lengths and diameters are expressed in mm.

specimen	length	diameter	no. elytra	other inclusions	comments
ZPAL AbIII/3402 (lower interval)	54.5	22	>18	Beetle remains: two tibiae, a carabid prosternum and two pronotums. Abundant exoskeletal fragments.
ZPAL AbIII/3408 (upper interval)	>37.5	22	>15	An abdomen of an unknown insect, and enigmatics including a curved object with denticles.	The coprolite is in a concretion and is not complete.
ZPAL AbIII/3409 (lower interval)	40	19	2	Small fragments of possible insect origin. Most inclusions are small and poorly preserved.	Various internal structures including secondary mineralized voids and a heterogeneous matrix.
ZPAL AbIII/3410 (upper interval)	31	16	>10	An abdomen of an unknown insect and an apparent exoskeletal plate of an insect thorax.
ZPAL AbIII/3411 (lower interval)	39	19	3	Very abundant small potential insect fragments.
