Even behavior is sometimes preserved by being "frozen" in time, for example, a specimen of Marrella splendens Walcott, 1912 was caught in the act of molting [ 9], several specimens of Ottoia prolifica Walcott, 1911 were preserved while scavenging together on a carcass [ 8, 10], and trilobites have been preserved within the empty tubes of priapulid worms [ 11].
(A) A specimen of L. longissimus (B) Example of a nemertean stylet apparatus (C) Stylized and simplified phylogenetic tree of Lophotrochozoa, displaying the relationship to Mollusca, wherein the cone snails are found, and the subdivision of the nemertea clade into enopla and anopla classes.
For example, all specimens of the Iberian Range were pooled into a single population when, in fact, there are two distinct lineages in this region.
Within specimens of Triceratops, for example, "A" individuals have skulls approximately 0.3 m in length; F-size skulls are approximately 3.0 m in length.
A whole series of pterosaurs that represent intermediate forms between the basal and derived groups are known in large numbers (Darwinopterus being the key example, one specimen of which is also preserved in association with an egg).
As an example, the juvenile specimen of Strobilopterus princetonii shows that the terminal podomere of the paddle is reduced in earlier instars in contrast to the larger podomere recognised in the adults.
For example, a lymphoma specimen that coexpresses high levels of MYC and BCL2 proteins may respond better to a combination regimen that targets both proteins.
An example of a beautiful specimen of Coelophysis is depicted above.
For the example above of a specimen with a spatial frequency of 1,000 lines per millimetre, the required N.A. to collect the diffracted light would be 0.55.
The Essig Museum, for example, contains specimens of bees, together with the pollen they were carrying and their parasites, from nearly every year since 1910.
