The smallest specimen of Triceratops found during this project is a partially complete skull that is half again the length of the smallest previously known skull [20].
That's what an international team of researchers observed when working with single cells and small specimens of mouse gut: Lectins bound to the membrane-repairing proteins of intestinal epithelial cells, effectively inactivating them.
Especially informative was his observation that in a male specimen of L. antarctica, the most anterior gonad was not completely separated and still partially fused with the posterior ones, and small specimens of L. antarctica only had four rather than five gills.
In several smaller specimens of Gorgosaurus, the tibia was longer than the femur, a proportion typical of fast-running animals.
Within comparable size stages (>21 mm to adult), smaller specimens of both catfish species show better high-frequency hearing (4 6 kHz in L. cyclurus and 5 6 kHz in S. schoutedeni), and larger specimens show better low-frequency hearing (50 Hz–1 kHz).
The comparatively large size, in some cases the pattern of epibionts of the conch, and the lack of small specimens of endocerids, tarphycerids and other non-orthocerids in the black shales suggest that these occurrences consists of drifted shells.
Fish were fed frozen chironomid larvae and artificial food (granulate, flakes and tablets); the small specimens of groups XS were also fed Cyclop-Eeze® (freeze-dried copepods, Argent Chemical Laboratories, Redmond, WA, USA).
Nomarski images were taken of small specimens of Ciona, which were sedated and then microdissected and mounted under a coverslip, fixed in situ with 4% PFA and then transferred through a series of glycerol solutions of increasing concentration, up to 100% glycerol.
Determination of the range of input total RNA necessary to achieve reasonable fidelity and reproducibility is crucial for researchers dealing with very small specimens of human tissue.
Because of the small specimens of verrucous hyperplasias and normal oral mucosas, only one 1.5-mm-diameter core for each case was selected.
