The name of the member of a research group who authorizes the entry of information into the database. This may or may not be the same as the Data Coordinator. It is intended that the currently empowered Authorizers be a small and restricted set of research group members who work closely with the database. Their job is to certify that the data prepared by the Data Coordinator(s) meet the current standards for scientific accuracy and have been entered logically. They are also responsible for catching major errors of a scientific nature, inconsistencies, and misunderstandings on the part of whoever filled out the datasheet. No datasheet can be entered without an Authorizer.

DESCRIPTION
The data for each entity are prepared by or under the supervision of a particular researcher (or group of researchers). This (these) person(s) is designated the Data Coordinator, and is the primary source of the information and is responsible for its accuracy. Data Coordinators may or may not also be Data Authorizers. Data Coordinators possess such rights over the data as the Consortium has decided in its general policy on the subject. Briefly, for entities designated as "private", the Data Coordinator's data are treated as a collection that the Data Coordinator is actively working on. Thus, the Data Coordinator must be consulted/informed when other researchers use the data in some project intended for publication. The Data Coordinator may deny permission for such use. The Data Coordinator may initially or at a later time designate the status of a species or locality as "public". In this case, the data become "public domain" and can be used by anyone with access privileges to the database, for any purpose, without informing or obtaining permission from the Data Coordinator. The Consortium has established a time period (5 years from date of entry or last modification) after which data of a particular entity will convert to "public" status, unless there are compelling reasons to retain private status.

DATA TYPE

DESCRIPTION
The predominant, or most important or most characteristic, food type in the diet of the species, at a detailed level of resolution. At this scale, the diets of many species will not be clearly distinguishable from one another using only a single term for the most common dietary component. Nevertheless, highly variable food-type categories often delineate distinct ecological/adaptive/functional types (as in the case of mixed browsing/grazing ungulates). That is, calling something a "frugivore" may not explicitly describe other components of its diet, some of which may be of adaptive importance to the species; it does not allow one to distinguish among species within the frugivore category, either. But it does allow one to place the species between omnivores or insectivores, on the one hand, and browsers, on the other.
Neontologists often are after detailed descriptions of particular species' diets, rather than the ability to make broad comparisons across species, and their attention to detail reflects this interest. Remember that we are not trying to feed fossil species, but rather to get some idea of what they were doing in the ecosystem relative to others. Our categories are necessarily coarser than what many neontologists would desire, but we are not after detailed niche overlap analyses with these categories.
Explanations for specific terms are given below. See also Diet 1, Diet 2, Relative Fiber Content, Selectivity, Food Processing Mode, Digestion.

DESCRIPTION
The primary way in which the animal mechanically processes food either prior to or in conjunction with digestion. Oral processors comminute food, reducing it to digestible-sized particles, primarily through chewing in the mouth. (e.g., herbivorous mammals, advanced ornithopod dinosaurs.) Gut processors, on the other hand, use their mouths and dentition (if any) primarily to obtain pieces of food to swallow, and do little processing in the mouth. Rather, most mechanical breakdown occurs in the digestive tract. (e.g., sauropod dinosaurs, birds, turtles). These distinctions are mostly of importance for herbivorous vertebrates, but even carnivorous vertebrates differ in the degree to which the dentition is used to slice meat.

DESCRIPTION
For non-aquatic, non-aerial species the terrestrial substrate upon which locomotion characteristically takes place. "Arboreal" describes species that almost never come to the ground, or, if they do, it is almost always for the purpose of dispersing to another tree or trees. "Scansorial" is a broad category including those species that habitually use both trees and the ground in their movements. At the non-arboreal extreme, it includes species that rarely in practice use the trees, but are not morphologically prevented from doing so. [This category may eventually have to be split to distinguish species that exhibit some arboreal adaptations (e.g., squirrels), from those that could climb in a limited way if they had to (e.g., lions).] "Surficial" refers to those creatures who use only the ground surface in locomotion (e.g., sauropods, wildebeeste).
For aerial species, we allow a distinction to be made here between powered and nonpowered flight. Powered flight refers to active flying (by more or less continuous wing-flapping), whereas nonpowered flight refers to gliding, parachuting, or soaring, where the force of gravity and wind currents are used as the major propulsive forces. Although most soaring vertebrates are also capable of powered flight (at least in a limited way to get aloft), if the species' predominant mode of locomotion is soaring, then the species belongs in the nonpowered category for purposes of Locomotion 2. The categorization of flight locomotion in Locomotion 2 and Locomotion 3 is based on Norberg (1985).

This field describes the morphology of mammalian molar crowns, and is complimentary to the Tooth Shape - Multicuspid field. The latter presents a traditional classification of molar crown types (and other multicusped teeth) for vertebrates. Molar Crown Type, in contrast, uses a more recently developed classification scheme that is currently restricted to mammals. The scheme is phylogenetically neutral and descriptive, allowing functional interpretations and interpretations of underlying developmental mechanisms (see Jernvall, 1995). Currently, the values for the field consist of five-letter alphanumeric codes, described in Jernvall, et al. (1996), and the reader is referred to that paper for further explanation.

It could also be based, less directly, on other aspects of the organism's biology -- for example, sexual dimorphism in sexual display or combat features. If so, indicate "soc" here and give details briefly in the Comment field. The choice "sol" (solitary) is allowed for completeness, but ordinarily there will be no positive evidence for solitary behavior, so the alternative to "soc" is usually a blank.

DATA TYPE

DESCRIPTION
The relative amount of plant fiber in the food of the species. Plant food can be divided into cell contents such as sugars, proteins and storage carbohydrates, which are directly digestible by vertebrates. Plant cell-walls, however, are composed of material ("fiber") partially digestible only by microbial fermentation. Thus, the higher the fiber content, relative to the amount of energy contained in the easily-digested portion, the harder it is to obtain energy from the forage and the poorer the "quality" of the food on a per-unit basis. In addition, the proportion of the fiber digestible by fermentation also varies among plant species, plant parts, and growth stages. This field describes the food as having high, medium, and low levels of fiber. It is intended as a rough indication of the nutritional quality of a species' diet. It refers only to herbivorous diets, or the plant portions of omnivorous diets. (The field basically functions to group various Diet 3 categories by relative fiber content.)

The species name of the species. It is always entirely in lower case. Species may also be recorded as "sp.", "indet.", or preceded by "cf." to indicate different levels of uncertainty in assignment. These three strings are the only ones that the graphical interface recognizes as alternatives to Linnean names. "sp." implies that it is known that this is a new or separate species, but that it currently has no formal taxonomic name; use "indet." for a species that is not identifiable at the species level. "cf." is to indicate any of the many tentative assignments (including "aff.", "near", ? species, etc.). "cf." entries always are recorded as separate species, not as instances of the referred species.

Every species or locality record in the Database at any moment is assigned a status, which indicates the level of access permitted to that record. Currently, the value "public" indicates that the record is essentially "public domain" and will be made available without restriction in the public domain version of the ETE Database. The value "private" indicates that the record will be accessible only to those researchers who have access to the ongoing working database. Records will ordinarily be entered with "private" status until the members of the Project (q.v.) that has generated them releases them to the public. The Data Coordinator (q.v.) for each record is ultimately responsible for any changes of its status. Additional values for status may eventually be added if it becomes necessary to specify in finer detail the access level of an entity.

DESCRIPTION
An indication of hypsodonty (tooth crown height) or the nature of other adaptations to deal with the problem of lifetime tooth wear. Tooth replacement, Tooth plates, and Hypselodont (ever-growing teeth) are absolute descriptors. The terms Brachydont, Mesodont and Hypsodont refer to different degrees of crown height of (mammalian) cheek teeth, and are subject to a variety of interpretations. Hypsodont (high-crowned) teeth may be defined objectively as those where the antero-posterior length is exceeded by the dorso-ventral height (Janis & Fortelius, 1988). "Somewhat hypsodont" teeth, intermediate between brachydont and hypsodont, are referred to as "mesodont," but there is no corresponding objective definition of this term. Quantitative indices of hypsodonty have been used (Janis, 1988), and might prove superior to the classification scheme presented here. Thus, this field is currently subject to further development.

DESCRIPTION
A description of the morphology of the tooth crown, for multicusped teeth (if present). In concert with the other tooth morphology fields, this may allow functional interpretations to be made independently of whatever has been entered in the diet fields. Terminology for tooth-crown morphology is most highly developed for extant and fossil mammals, but no system has gained universal acceptance. The following reflects a compromise among many competing traditional systems, and is based partly on Fortelius (1985) and Janis and Fortelius (1988). This field is currently subject to further development. Improved nomenclature for some mammal groups, such as rodents and insectivores, might be more functionally indicative. Also, an expanded list of terms would be useful to characterize more fully the variation found among nonmammalian terrestrial vertebrates -- dinosaurs and therapsids in particular. The similar Molar Crown Type field is based on an alternative descriptive classification scheme, and currently applies only to mammals.

DESCRIPTION
At times the occurrences of the same species at different localities will still differ in some ecologically meaningful way. For example, the same named species may be of substantially different size in different fossil localities. In order to record the size appropriate to each locality, one must somehow separate the two species occurrences -- as if they were two separate species. At other times, adequate identifications may be unavailable, or systematic work needs to be done, such that the best one can do is to identify to some higher taxon (e. g., Somegenus sp.). In such a case, "Somegenus sp." is what the computer will search on when a species list is entered. But there may be many undescribed species of Somegenus, each different in ecologically meaningful ways, and found in a variety of localities. Yet, they all have the same generic and specific name as far as the computer is concerned. They need to be treated individually.
The unique field is the way to do this. In addition to Genus and Species, this field is also searched when a species name is input as part of a species list. In effect, the ETE Database uses "trinomial" designations for its "species". Thus, to separate occurrences of Somegenus, all one has to do is to specify an entry in the unique field. It might be a letter or a number, or an abbreviation for a locality, or any string of 30 characters or fewer that will serve to identify it uniquely. Remember that other people might be working with Somegenus as well, so naming a species "Somegenus sp. A" (i.e., the unique field = "A") might inadvertently identify it incorrectly as another one already in the database. One fairly safe solution would be to include some kind of locality, regional, or temporal designations within the 30-character string -- increasing the probability that the unique field will really be unique.
Data Coordinators must keep track of their own usages and assignments using this field, and they should become aware of the ways in which the species (or close relatives) that they are working with may have already been entered by other workers. The computer cannot sort out a nomenclatural mess where two different things have been given the same name by mistake. On the other hand, excessive use of the unique field, resulting in a situation where all or most occurrences of a species are distinguished as unique, should also be avoided. This is surely unnecessary, takes up valuable storage space, and can also become confusing to other workers.
There are, however, a number of common situations that require the use of the unique field. These include cases where useful information is contained in assignments to Linnean hierarchical levels other than those allowed in the ordinary data fields, such as subfamilies, tribes, subgenera, subspecies and the like. Most importantly, an entry in the unique field is required if both genus and species are indeterminate, but assignment can be made to some higher taxon (as is usually the case). This is because the genus and species fields alone do not specify the taxonomic level and taxon to which the assignment can be made (e.g., we need to be able to distinguish "Elephantidae indet. sp." from "Sauropoda indet. sp."). The simplest solution is to put the lowest higher taxon to which the assignment can be made in the unique field ("indet. sp. Edaphosauridae").
The following examples show the recommended conventions for entering unique field information for vertebrate species.
