  Pleistocene era Florida Gulf Coast  habitat reconstruction. This was a mural prepared for the University of Florida Museum of Natural History. Details are in the two images that follow immediately below.
 This is a  left side detail  of the  Pleistocene era Florida Gulf Coast Marine mural  prepared for the University of Florida Museum of Natural History.  Amongst the  “chief vertebrate actors”  are a    Manatee   (Trichechus manatees),  a  Goliath Grouper   (Epinephalus itajara),  a    Barracuda   (Sphyraena barracuda) , a  Pelican   (Pelecanus erythrorhynchos) , diving after a school of  Mullet   (Mugli cephalus) , a  Nurse Shark   (Ginglymostoma cirratum) , a  Stingray   (Dasyatis sp.) , a  Porcupine fish   (Diodon sp.) , and a  Skate   (Raja sp.) .  A  Great White Shark  is seen in the distance. Invertebrates include corals, crabs, silver dollars, clams, oysters, and marine snails.
  This is a    right side detail    of the    Pleistocene era Florida Gulf Coast Marine habitat mural    prepared for the University of Florida Museum of Natural History. The “chief vertebrate actors” on this side of the mural include the    Caribbean Monk Seal    (Monachus tropicalis), a    Hawksbill Sea Turtle    (Caretta caretta), and a school of    Mullet    (Mugil cephalus). Among the invertebrates in the sea grass meadow, the following mollusk species are present: Arcinella cornuta, Eupleura tampaensis, Hexaplex fulvescens, Fasciolaria okeechoensis, Liochlamys bulbosa, Turbinella hoerlei, and Strombus leidyi.

 Illustration of the Tyner Farms Miocene era site in Northern Florida near the Suwannee River. The habitat is known for its mammalian megafauna including proboscideans, bone-eating canids, tusked artodactyls, and giant ground sloths. This mural is part of a permanent installation at the  University of Florida, Museum of Natural History.  Details are described in the two images that follow immediately below.
 This image shows a more detailed view of the left side of Tyner farms Miocene habitat reconstruction. In the foreground, a small,  pronghorn-like  female antelope,   Pediomeryx hemphillensis   leaps forward, seemingly out of the picture plane. Behind her, the tri-antlered male   Pediomeryx hemphillensis     leaps upwards crossing the limestone cliff face. The Miocene era horse   Dinohippus   is slightly to her right and in the immediate foreground is the large land tortoise   Hesperotestudo   feeding on Palmetto fruits. At middle distance on the left is the dog-like hyena   Borophagus pugnator.   In the background, a female  North American Rhino   (Aphelops mutilis)  watches as her calve flees the water when an  Alligator  ( Alligator mefferdi)   ,   holding a captured Pediomeryx in its jaws, swims in that direction.
 This is a more detailed image showing the right side of the Tyner Farms Miocene era mural. A giant  Ground Sloth   Thinobadistes wetzeli)  is shown feeding upon a  Black Tupelo   (Nyssa)  at the center of the image and on the right side foreground, diminutive  Musk-deer   (Pseudoceras sp.),  are depicted feeding upon  Saw Palmetto  fruits ( Serena repens).  At left, in the background, a  Shovel-tusk Probiscidean   (Ambelodon britti)  drinks from a fresh water lake .  At left, in middle distance, an ancient horse  (Dinohippus sp.)  is ascending the incline of face of a limestone cliff edge.

 This is a reconstruction of   Orienantius ritteri,   a basal avian (  Enantiornithine   )  from the Early Cretaceous of China.  It is believed to have had flying capabilities similar to living birds.   Orienantius ritteri   is shown near the end of a downstroke in level flight.
   New York Times   Science Section illustration depicting the three vertebrate groups which separately developed powered flight as examplesof  convergent evolution:  avians (Clade: Ornithurae,   Class : Aves) , pterodactyls (Clade:  Pterosauromorpha ), and bats  (Class:  Mammalia )
   Junornis houi     This is a reconstruction of the sparrow-sized ancient bird    Junornis houi    from the early Cretaceous era of Inner Mongolia.    Junornis houi    retained teeth in both its upper and lower jaws as well as wing claws (possibly used for assistance in climbing amidst tree branches). This avian is shown at the beginning of the upstroke in level flight with both the primary and secondary feathers (remiges) are numbered for clarity.
