Some of the most basic questions of sea turtle life history are also the most elusive. Many uncertainties surround lifespan, growth rates, maturity and spatial structure, yet these are critical factors in assessing population status. Here we examine the keratinized hard tissues of the hawksbill Eretmochelys imbricata carapace and use bomb radiocarbon dating to estimate growth and maturity. Scutes have an established dietary record, yet the large keratin deposits of hawksbills evoke a reliable chronology. We sectioned, polished and imaged posterior marginal scutes from 36 individual hawksbills representing all life stages, several Pacific populations and spanning eight decades. We fit von Bertalanffy growth function VBGF models to the results, producing a range of age estimates for each turtle. We find Hawaii hawksbills deposit eight growth lines annually range 5—14 , with model ensembles producing a somatic growth parameter k of 0. Recent bomb radiocarbon values also suggest declining trophic status. Together, our results may reflect long-term changes in the benthic community structure of Hawaii reefs, and possibly shed light on the critical population status for Hawaii hawksbills. The harvest of hawksbill sea turtles for the global tortoiseshell trade was enormous [ 1 ] with some estimates that 30 turtles were trafficked annually from to [ 2 ].

Just-hatched sea turtles scurry towards the safety of the waves, leaving trails similar to those seen in newly described fossils. The first known record of baby sea turtles making their run for the ocean has been revealed by fossilized tracks dating back about , years. After emerging from eggs buried in sandy nests, sea-turtle hatchlings race towards the ocean, which offers refuge from land-based predators. Credit: Jan de Vynck. Some of the imprints resemble those made by modern loggerhead sea turtles Caretta caretta ; other traces look like those made by modern leatherback turtles Dermochelys coriacea.
Turtles are the oldest living reptiles, with the earliest known turtle dating back million years. The western pond turtle is one of only two native turtle species in.

Salvatore “Turtle” Assante   is a fictional character on the comedy-drama television series Entourage. He is played by Jerry Ferrara. He is the only one of the main characters who is not directly involved with the acting business. Turtle is Vincent’s driver and takes care of issues around the house. He brings street smarts and an urban flavor to the group and is a frequent user of marijuana and supplier to the rest of the group.
Usually he and Drama stick together and do their own things while E and Vincent are doing business. Turtle often finds the good in all bad situations and brings a relative calm to the group. Turtle’s importance is at times overlooked, but his insight and personal connections sometimes solve difficult issues.
For example, his acquaintance with rapper Kanye West allows the guys to fly to the Cannes Film Festival in Kanye’s private jet after their previous plane was too small to fit everyone. He also was able to have four seats reserved in the back of a movie theater so the group could see Vince’s new movie Aquaman by offering a copy of the video game adaption of the movie.
His working status and questionable looks prevent him from being more appealing to women, which the guys joke about on many occasions, particularly Drama, who isn’t any more appealing than Turtle. Turtle loves sneakers, especially rare Air Force 1s. His appeal to women changes when he starts dating Jamie-Lynn Sigler , when he catches the attention of a couple of sorority sisters at UCLA.

If beauty was considered a curse, the hawksbill sea turtle would be the poster child. Though hawksbills face a myriad of threats from human activities, as do all sea turtles, the demand for their shell remains a serious obstacle to their continued survival. Though the importation of turtleshell items is illegal in the United States these items are the most commonly intercepted products by US Customs agents from tourists returning home from the Caribbean.
Since ancient times, hawksbills have been hunted for their beautiful shell which is made up of colorful overlapping scales in shades of gold and brown and orange, called scutes. The scutes are polished and used to make combs, jewelry, sunglasses, ornaments, and other luxury and decorative items. In Japan, bekko combs are still worn as part of their traditional wedding dress.
Whole turtles are also dried and sold intact as a wallhangings and curios. In the last couple of decades, large shipments of hawksbills headed for the black market have been intercepted by enforcement agencies around the world.

A fossilized skeleton of a turtle, dating back about million years to the dawn of the dinosaur era, has been found in China, shedding new light on the earliest evolution of turtles. This is the oldest turtle ever discovered with a toothless beak. The turtle, more than 2 meters long, with a short trunk, had no shell on its back and abdomen, said Li Chun, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences.
Found from the late Triassic deposits of Guanling County in Guizhou Province, southwest China, it has been named Eorhynchochelys, meaning “first turtle with a beak,” and featured in the latest issue of the academic journal Nature.
