Some believe that insects evolved from the an ancestor that gave rise to the malacostracans, a group of crustaceans that include crabs and shrimp, while others point to a lineage of less commonly known crustaceans called branchiopods, which include, for example, brine shrimp.
Because the brain anatomy of branchiopods is much simpler than that of malacostracans, they have been regarded as the more likely ancestors of the arthropod lineage that would give rise to insects.
The other group, which was generally favoured, thought they came from a class of crustaceans called branchiopods, which include brine shrimp and fairy shrimp.
Strausfeld said: "There have been all sorts of implications why branchiopods shouldn't be the ancestors of insects.
Fairy shrimp, tadpole shrimp, and clam shrimp are all capable of this impressive feat, a skill not uncommon among a category of animals called branchiopods
The probable trace makers, arthropods such as branchiopod
crustaceans, are potential producers of bilobate trails such as Didymaulichnus or unilobate trails such as Helminthopsis.
Denton Belk graciously identified all the large branchiopod
specimens from my field work and provided guidance and technical information during the preparation of this work.
taxa that were found during the study (Table 1) have become suited to temporary environments through various physiological, behavioural, life-history and structural adaptations (De Roeck et al.
Ultrastructure and ion permeability of the two types of epithelial cell arranged alternately in the gill of the fresh water branchiopod
Caenestheriella gifuensis (Crustacea).
The particular style of molar ornamentation links the Mount Cap fossils to a clade of crown-group (pan)crustaceans that includes branchiopods
, malacostracans, and hexapods, and thus provides a crucial calibration point for arthropod phylogeny, as well as the earliest record of an arthropod with a sophisticated particle-feeding ecology (Harvey and Butterfield 2008).
In cooperation with natural heritage program members in all 50 states, NatureServe has compiled, and maintains, a detailed database of over 21,000 plant and animal species in the United States, including nearly 16,200 vascular plants, approximately 2,550 native vertebrate animal species (including mammals, birds, reptiles, amphibians, and freshwater fishes), and a wide spectrum of invertebrates (including "all 2,600 species in the following groups: freshwater mussels, freshwater snails, crayfishes, large branchiopods
, butterflies and skippers, underwing moths, tiger beetles, and dragonflies and damselflies").
