Hello, Frank Indiviglio here.   Recent studies of a creature known as Nyasasaurus parringtoni indicate that dinosaurs may have appeared over 240 million years ago – 10-15 million years earlier than was previously believed.  Its fossils, unearthed in Tanzania, also shed light on where dinosaurs first arose and how they spread to new environments.  I’ve also summarized some other recent paleontological surprises concerning the oldest dinosaur nest, dinosaur flea, bird, and organic molecule.

Dinosaur or Silesaur?

Nyasasaurus parringtoni lived in the Mid-Triassic period, alongside dinosaur-like reptiles known as Silesaurids (please see drawing).  The dating of its fossils to this period is significant, because true dinosaurs were likely very rare at the time. 

Some paleontologists believe that Nyasasaurus is a Silesaurid rather than a dinosaur.  However, its upper arm bone bears a bony crest that held the shoulder muscles in place.  Known as the deltopectorus crest, this structure is found in all other dinosaurs, but not in Silesaurids. Read More »

Hello, Frank Indiviglio here.  In 2010, I highlighted a study that documented steep declines in a number of snake species.  Despite disturbing similarities to the “Disappearing Amphibian Crisis”, the snake situation seems not to have generated widespread concern.  In my own career as a herpetologist, opportunities to become involved in snake conservation were also limited. Although I was fortunate enough to work in programs designed to bolster the populations of several species, including Green Anacondas, Indigo and Hognose Snakes, most such efforts were short-lived.  I was pleased to learn, therefore, that a partnership of several major conservation organizations has made the plight of the world’s snakes a priority for the year 2013.

The Year of the Snake…your input needed

The Year of the Snake effort is spearheaded by Partners in Amphibian and Reptile Conservation, and was preceded the Year of the Turtle and the Year of the Lizard.  PARC will be joined by the Center for Conservation Biology, the Orianne Society and other notables (please click here for a complete list).  In addition to field research and captive breeding programs, public education will be a major component of each group’s activities.  I was very glad to see that input from interested non-professionals will be solicited.  This is an all-too-rare step, despite the fact that professionals, being limited in both numbers and financial resources, cannot begin to address the myriad conservation needs of the world’s threatened snakes.  Please see “What Can I Do”?, below, if you wish to participate.

Hello, Frank Indiviglio here. As a child, my information on the Goliath Frog, Conraua goliath, was limited to a few brief sentences hidden away in various books, but this was enough to spark my interest.  Eventually, a life-sized sculpture of one at the American Museum of Natural History (please see photo) gave me some idea of just how impressive a creature it was, and my desire to learn more intensified.  Happily, I found a job at the Bronx Zoo shortly after a group of Goliath Frogs arrived there from Cameroon, and I was able to indulge my passion.  One of my new charges spanned 25 inches with legs extended…nothing, not even the enormous African Bullfrogs and Marine Toads (or, for that matter, Leatherback Turtles!) that I had already handled prepared me for the sight of that amazing animal.

The Goliath Frog Exhibit

I first started working with Goliath Frogs in 1983, at which time we knew little about their natural history or captive needs. Unfortunately, not much has changed since, although field research completed in 1985 (Sabater-Pi, Contribution to the Biology of the Giant Frog, Amphibia-Reptilia, 6(2), 143-153) has filled in some of the blanks. 

The new Goliath Frogs, collected as adults in Cameroon, were shy and high strung, and prone to wild, injury-producing leaps when disturbed. We assumed, therefore, that the zoo’s noisy, crowded Reptile House would not prove an ideal location for their exhibit. Therefore, the curator commandeered an exhibit at the relatively-ignored Aquatic Bird House. Goliath Frogs are habitat specialists, so their exhibit was arranged accordingly, and outfitted with a waterfall and a swift, rocky stream bordered by dense thickets of live plants. In keeping with what little information was available, the water was maintained at a slightly acidic pH. Read More »

Hello, Frank Indiviglio here.  An amazing array of newly-discovered reptiles and amphibians grabbed our attention this past year.  The unexpected discoveries of an undescribed Leopard Frog in New York City and a Rainbow Skink in an Australian backyard reminded us that wonderful surprises surround us, if only we take the time to look and learn.  Frogs that dye human skin yellow, snakes that specialize in eating only eggs or snails, iridescent skinks sporting tails twice their body length…the list is simply astounding.  Today I’ll highlight a few that have especially captivated me; please post your own favorites (whether covered here or not) below.

Australian Rainbow Skinks

2012 was designated as the Year of the Lizard by several conservation organizations, so I’ll lead off with 3 new skinks that turned up in Queensland, Australia.  The brilliant colors of breeding males lend these tropical lizards their common names (please see article below). 

The Elegant Rainbow Skink, Carlia decorata, was well known to folks in Townsville, Queensland, as a common garden resident. Upon taking a closer look, however, herpetologists realized that the colorful creature was an undescribed species. Read More »

Hello, Frank Indiviglio here.  Invertebrate enthusiasts have learned to expect the discovery of fantastic new species on a regular basis.  But even old timers such as I were shocked by some that came to light this past year. Large, claw-bearing Cave Robber Spiders, giant bio-luminescent roaches, brilliant arboreal tarantulas, neon-colored freshwater crabs, dive-bombing wasps…the list boggles the mind.  Today I’ll highlight a few that have entranced me; please post your own favorites (whether covered here or not) below.

Cave Robber Spider, Trogloraptor marchingtoni

The Cave Robber Spider, arguably 2012’s most “otherworldly” discovery, turned up in a place not known for hiding unseen species – southwestern Oregon.  In fact, not a single new spider has been described in the USA in the past 130 years.  Read More »
