XArchaeopteryx lithographica



Size:500mm

Weight:0.8-1kg

Life expectancy:not known

When it First appeared: Late Jurassic period 150.8 million years ago

Location:The fossils of this bird/dinosaur where found scattered across Germany. A.lithographica most likely lived in the forest.



Taxonomy:

Class:Aves
Subclass:XArchaeornithes
Order:XArchaeopterygide
Family:XArchaeopterygidae
Genus:XArchaeopteryx
Species:XArchaeopteryx Lithographica

Diet:Most of this animals diet was insects.

Anatomy:Archaeopteryx lithographica is a transitional fossil. This fossil connects theropod dinosaurs with birds. Its avian traits are feathers, a opposable hallux, a furcula, which is the wish bone. and a pubis that is elongated an pointing backwards.

The theropod traits are the premaxilla and maxill is not made of keratin, the trunk region of vertebra are free, have pneumatic bones, which means they had air sacs like birds and dinosaurs, has teeth(which no modern bird has),long bony tail that is free, pubic shafts with a plate-like and slightly angled transverse cross-section(a trait that only dromeosaurs share with them), three unfused digits, Metacarpals free with wrist hand joint flexable, and cerebral hemispheres elongated ans slender which is situated behind the midbrain and does not overlap from behind or press down on it.

Behavior: Thanks to its scleral rings, we can tell that Archaeopteryx lithographica was durnal. It is not known if Archeopteryx was solitary or social. This animal may have either flew or glided.

Reproduction:Not known

Relationships with other animals:Not known



I am a dinosaur, because birds are dinosaurs anyway so it would not matter

Photuris lucicrescens(requested by TSG)



Size:5-20mm

Weight:20g

Life expectancy:2 months

When it first appeared:Not known

Location:This species of firefly lives in forest and urban areas in the united states.

Taxonomy:

Class:Insecta
Subclassicondylia
Infraclassterygota
Order:Coleoptera
Suborderolyphaga
Superfamily:Cantharoidea
Family:Lampyride
Genushoturis
Specieshturis lucicrenscens

Diet: P.lucicrensens eats other insects.

Anatomy:Like all members of Lampyridae, they are biolumiencent. The light is a cold light, which means it has no infrared or ultraviolent frequences. There light wavelengths can reach 510-670 nanometers. They use these lighst to communicate. The lights can flash thanks to the luciferose enzyme reacting to magnesum ions, ATP, and oxygen.

Behavior: P. lucicrenscens lives only but is social. The arthropods are most active at night and dusk, but will occasionally travel by day. They rest alone and will fly by themselves, but P.lucicrescens will fly in groups when they meet.

Reproduction: When ready to mate females will use a flashing of lights to signal they are ready. When the male finds his mate , he will mount her. The female will lay eggs on her back. The larvae also glow. THe eggs take 3-4 weeks to hatch.

Relationships with other animals: Males mus be wary of other members of Photuris as females of the genus eat males of other species of firefly. Humans use this animal for light and they keep them as pets.
