Topic: Anomalocarid


  
 Class Dinocarida
Since the anomalocarid bauplan appears to be more variable than previously assumed, efforts should be directed towards compiling a new, complete list of diagnostic characters for the family.
Part of the problem in adequately classifying the anomalocarids is that they developed a significant amount of derived features masking their ancestry after diverging from basal arthropods.
The assumption that the anomalocarid lateral lobe may be a true exopod is partly based on the presence of reported ventral, limb-like appendages being consistent with the gross morphology of the arthropod endopod.

Anomalocarids are the largest Cambrian animals known (some Chinese forms grew up to 2 m, and most of them were probably active carnivores (although recent thought posits one genus, Laggania, as a plankton-eating animal).
In the anime series Neon Genesis Evangelion, the eighth angel, Sandalphon, resembles (& was modeled on) an anomalocarid, with the addition of 2 extra, multi-segmented arms that have fingers shaped like an anomalocarid's feeding arms.
A monster resembling an anomalocarid appears in the first episode of the anime series This Ugly Yet Beautiful World.

 Species Accounts
I also graced the creature with eyes on stalks lateral to the mouth, as in the majority of anomalocarids.
This specimen of Opabinia regalis displays some of the clear similarities with anomalocarids: elongate, metameric body, bearing lateral swimming lobes, anterior stalked eyes (albeit 5 of them!), ventral mouth, anterior grasping organs (paired and spine-bearing at the distal end), even a dorsal fantail behind the swimming lobes.
However, some of the Chengjiang anomalocarid specimens are also smaller than those of the Burgess Shale, leading some researchers to claim that they represent juvenile specimens.

Anterior grasping limbs made it easy for an Anomalocaris to grab food and pass it to the mouth, which was on the underside of the head.
Anomalocarids are generally considered to be of the phylum Dinocarida.

 Background history on Anomalocaris part 2
Most other anomalocarid workers agreed (e.g., Babcock 1993, Collins 1996), but some (e.g., Hou, Bergstrom and Ahlberg 1995) claimed that anomalocarid mouthparts were not hard enough to deal with trilobites.
Anomalocarid arthropods have been reported from Cambrian fossil localities around the world, including the Burgess Shale formation in Canada, Rocky Mountain states of the U.S., Chengjiang formation in China, and the Emu Bay Shale formation in Australia.
Exceptional fossil preservation (At the Burgess Shale and Chengjiang in particular), skillful preparators, and comprehensive studies have revealed much about the palaeobiology of some of these formerly enigmatic animals, but much still remains to be clarified about their anatomy, biology and relationships.

 Opabinia & "Dino-carids"
If and why Opabinia has two pairs of stalked eyes seems to be a mystery to everyone, but one can't rule out the possibility that one pair is homologous to a pair of antennae.
The segmentation in Anomalocarids and Opabinia is very similar, both have biramous limbs (the upper branches modified into swimming flaps), and almost everyone notices the very similar tail fan.
And it is beginning to appear that wherever anomalocarids are found, so are Opabinia-like animals.

Many of the specimens also display sub-lethal predation scars, possibly as a result of attack from anomalocarids.
Since the evidence of anomalocarid predation is present, it is likely that future expeditions will recover specimens of these organisms from the Sirius Passet locality.

 Anomalocaris - Wikipedia, the free encyclopedia
Anomalocaris ("unusual shrimp") is an extinct genus of anomalocarids, which are, in turn, thought to be closely related to the Arthropoda.
Anomalocaris was a swimming creature which possibly used flexible lobes on the sides of its body to propel itself through the water.
The name Laggania was later used for another genus of anomalocarid.

 er, what's an Anomalocaridid? [Archive] - TONMO.com Forums
It is interesting to note that the earliest nautiloids that rose to the position of top predator and diversified massively in the subsequent Ordovician period appeared after the extinction of the anomalocarids.
One could almost argue that the molluscs had been held in check by the arthropods in the Cambrian, and it was only after a mass extinction that the molluscs were able to exploit the niches largely vacated by the arthropod predators.
The common concesus was that this specimen was in fact some form of anomalocarid though it lacked the characteristic front appendages.

I contacted the scientist and donated it because I believe rare specimens should be in museums and studied.

Collins named Class Dinocarida for anomalocarids back in 1996.
Anyway, I am currently trying to falsify two alternative hypotheses concerning Opabinia (that 5-eyed conundrum), namely that it is a "form genus", either an immature (larval) Anomalocarid or a dwarf male Anomalocarid.
I think these are real possibilities that apparently have not yet been considered.

Studying other specimens of the same Chengjiang species, Ramskold described the abdominal appendages in greater detail as 'three or more [postoral] limb pairs modified into large gnathobases which form part of the masticatory apparatus', and 'trunk limbs' with 'small, jointed clawed endopods' and exopods...modified into large lateral flaps'.
