Variably called Attributes or Elements in various media (Fossil Cards calling them Attribute Types, and the anime inconsistently saying "Element" and "Type" when mentioned at all). There are six main attributes and two special attributes for both Dinosaur and Move Cards in Dinosaur King, and are essentially universal throughout all media.
Though varied across the different media, Attributes work much the same. Other than Normal Moves, Move Cards can only be used by dinosaurs with the same Element. The 6 main Elements form a "ring" of advantage/disadvantage, each being strong against the one after it and weak against the one before it, but are at a neutral nonadvantage to all others, including themselves; this means that one Element of Moves is slightly stronger and another is slightly weaker against each Element of dinosaur. The precise scaling factor is unknown in the arcade game. In the DS game, bad/good match-ups result in 80% and 120% regular damage respectively, but are based directly on the attacking dinosaur's Element whether they are using a Normal or Super Move. In the anime, this order is represented by the arrangement of the Stone Tablets when placed together, though the amount of damage dealt by Moves rarely reflects the Elements involved. In the arcade and TCG, Move Cards are often ordered to be grouped by Element on their card lists, though only the TCG does this for Dinosaur Cards. The TCG also does not feature any mechanic to reflect Attribute effectiveness, simply specifying which Moves can be used by which dinosaurs.
- Fire Dinosaurs are strongest against Wind Dinosaurs (Wind spreads Fire), but weakest against Water Dinosaurs (Water puts out Fire). Their Move Cards involve attacks with fire. This element focuses more on power as they have more high-powered dinosaurs, and consists of tyrannosaurids, carcharodontosaurids, and the "biggest and meanest" of most other theropod groups (abelisaurids, metriacanthosaurids, allosaurids, megalosaurids).
- A website Dino Holder game featured Therizinosaurus as a Fire Dinosaur, implying that this is the original Element of Therizinosauridae (possibly because their bulky build prevents them from executing many Wind Moves convincingly). Megalosaurus was also probably originally a Fire Dinosaur due to its arcade introduction animation.
- Water Dinosaurs are strongest against Fire Dinosaurs (Water puts out Fire), but weakest against Lightning Dinosaurs (Water conducts electricity, like Lightning). Their Move Cards involve attacks with water. This element consists of all types of sauropods (cetiosaurids, diplodocoids, and titanosaurians) (once thought to be aquatic) and the spinosaurid theropods (scientifically proven to be partially aquatic), but two of their Moves summon ichthyosaurs and a plesiosaur (both marine reptiles).
- Lightning Dinosaurs are strongest against Water Dinosaurs (Water conducts electricity, like Lightning), but weakest against Earth Dinosaurs (Earth blocks Lightning). Their Move Cards involve attacks with electricity. This element consists of the ceratopsians (horned dinosaurs), mostly the ceratopsids. Their electrical weapons usually resemble human tools, such as anchors and spears.
- A website Dino Holder game featured Pachycephalosaurus as a Lightning Dinosaur, implying all of Marginocephalia (ceratopsians and Pachycephalosauria) have the Element.
- Earth Dinosaurs are strongest against Lightning Dinosaurs (Earth blocks Lightning), but are weakest against Grass Dinosaurs (Grass grows on Earth). Their Move Cards often involve attacking with rocks or glowing purple crystals. This element consists of the thyreophorans (armored dinosaurs) like the stegosaurians and ankylosaurians (nodosaurids, polacanths, and ankylosaurids).
- As a nodosaurid, the Pawpawsaurus would have been an Earth Dinosaur before being turned into a Secret Dinosaur.
- Grass Dinosaurs are strongest against Earth Dinosaurs (Grass grows on Earth), but weakest against Wind Dinosaurs (Wind blows Grass off the ground). Their Move Cards involve either attacks with plant life or using other dinosaurs to boost their own power or attack for them. This element consists of hadrosaurids (duck-billed dinosaurs), earlier iguanodontids, and their other ornithopod relatives, but many of their Move Cards summon a diverse variety of dinosaurs, like giant sauropods, even including pterosaurs and a plesiosaur (which aren't dinosaurs).
- Wind Dinosaurs are strongest against Grass Dinosaurs (Wind blows Grass off the ground), but weakest against Fire Dinosaurs (Wind spreads Fire). Their Move Cards involve attacks with wind and/or emphasize attacking quickly and repeatedly without letting the opponent recuperate from the previous attack before the next one hits. This element consists of small- to medium-sized theropods of almost all families, including many that also have Fire Dinosaur members (ceratosaurids, megalosaurids, coelophysoids, dilophosaurids, abelisaurids, allosaurids, metriacanthosaurids, neovenatorids, ornithomimids, troodontids, and dromaeosaurids).
- Several Secret Dinosaurs were or likely were originally Wind Dinosaurs based on their size and arcade introduction animation (Deinonychus, Eoraptor, and Cryolophosaurus).
- Secret Dinosaurs are very powerful and have no elemental weaknesses. In the anime, they glow with a blinding rainbow aura and are all artificially strengthened or specially trained individuals. All Secret Dinosaurs (except Eoraptor) each have 3 of their own unique Secret Moves, and all of these attacks (except Pawpawsaurus') involve a glowing rainbow aura in some way (though not all feature in the anime). There are very few Secret Dinosaurs, and members can come from any dinosaur family, though most are theropods. Some Secret Dinosaurs wouldn't fit comfortably in any of the six main elements using their present definitions, though for others, their otherwise "native element" is more obvious.
- Normal Move Cards can be used by any dinosaur, and usually feature simple physical combat or other non-elemental powers. Unlike other Attributes, Normal is in most Dinosaur King media portrayed as the lack of an Attribute rather than being a distinct type of power, the anime showing an empty Element space on the cards and the DS game listing their Attribute as "None".
- There are no playable dinosaurs from this Attribute. "Normal Dinosaurs" only appear in certain Normal Move Cards and either assist your dinosaur in battle or battle for them for the turn the Move activates. They can be from any dinosaur or pterosaur family. A yellow exclamation mark on a purple square is used as their element symbol in the Kyoryu-King Museum, although the same symbol is used to identify most Normal Moves, even those that don't involve these dinosaurs. Velociraptor in the anime notably initially lacked an element, so it may have been the only known Normal Element non-Move Card Dinosaur.
- Grass is the only Attribute that is not associated with any secret dinosaur as its original Element.
- In the anime, the interactions with the Attributes have often been left out, especially in relation to Grass and Wind. No Wind Dinosaur in the anime defeated a Grass Dinosaur, but in return also no Grass Dinosaur in the Anime defeated a Wind Dinosaur.
- The native Element of the Pterosaurs has never been revealed. Since they can fly, It is probably Wind, but Water would also be possible, since many members lived on the coast and ate fish.
