Synapsids were the world’s first-ever terrestrial megafauna but the vast majority of these giants were doomed to extinction. However, some lived on, keeping a low profile among the dinosaurs. And now our world is the way it is because of the time when the synapsids struck back.

Summary: A world-first study has found an alternative to antibiotics for treating bacterial infections in green sea turtles.
Researchers at the JCU Turtle Health Research Facility have conducted a first-of-its-kind study using what’s known as phage therapy as an option for bacterial infections in green sea turtles.
Phage therapy uses so-called ‘good viruses’ (bacteriophages) that occur naturally in the environment and kill bacteria.
“Green turtles rely on ‘good bacteria’ in their gut to extract nutrients from food,” said Dr Robert Kinobe, one of the researchers involved in the study.
“This creates a challenge when it comes to treating bacterial infections because if we administer antibiotics, it can destroy the ‘good bacteria’ and make the turtle’s health worse.”
Researchers at the JCU Turtle Health Research Facility applied ‘good viruses’ to green sea turtles and found that it was successful in eliminating the targeted ‘bad bacteria’ without hampering the non-targeted ‘good bacteria’.
“This shows that phage therapy can be safe and effective enough to manipulate or treat targeted bacteria in green sea turtles,” said Dr Kinobe.
A further complication, previously identified by the JCU Turtle Health Research Facility, is the existence of antibiotic-resistant bacteria in the guts of green sea turtles, which are found in several locations along the Queensland coast.
“Antimicrobial resistance is one of the most critical issues we face, which is why this finding of an alternative to antibiotics is so important,” said co-author Dr Lisa Elliott.
“Bacteriophages and phage therapy have already been suggested as an alternative for antibiotics in humans, but we also need to investigate its scope for treatment in animals.”
The research has been published in the Journal of Environmental Microbiology and opens the door for future applications of phage therapy as an alternative to antibiotics in treating bacterial infections in turtles and other marine animals.

From weird pink iguanas and painted insects; to mysterious new species; here are the STRANGEST Creatures of the Galapagos Islands!
Native to the islands, this is the only penguin known to exist north of the equator in the wild. It’s one of the world’s smallest species of penguin at about 19 inches long and weighing some 5.5 pounds. And due to its low population it’s also considered one of the rarest penguin species. Including other factors, the birds have many predators, including introduced species like dogs and rats. When they’re in the water, sharks and sea lions target the penguins.
Charles Darwin was not impressed with their looks and called them ‘imps of darkness’. They’re better known as marine iguanas that are found only on the Galapagos Islands … and are the only sea-going lizard currently known. Some of their marine adaptations include the ability to dive for more than 60 feet, and stay submerged for an hour. Marine iguanas normally subsist on seaweed. But when food gets low, experts say they can somehow shorten their own bones to make them smaller, and more energy efficient. Their dark coloration serves a couple of purposes. While it allows them to blend in with their environment, it also helps them quickly absorb heat after swimming in the cold waters.
It’s pretty easy to guess where this marine bird gets its name. While those feet look strange, they do serve a vital purpose when it comes to perpetuating the species. Males will strut around females, lifting their feet up and down in an unusual mating ritual. The guys with the brightest feet indicate greater fertility, and will usually win the ladies. Because the color fades with age, females mate with the younger males. The blue coloration is a result of a pigment the birds absorb from their diet of fresh fish. Unlike some of the critters on the list, these birds are not found only in the Galapagos … but experts say that about half of their global population breeds there.
There’s only one place in the world … and only one location in the Galapagos where you can see these uniquely colored lizards. In fact, the pinkish hue almost makes you wonder if this isn’t yet another one of those digitally created beasts … either that, or the reptile seems to have had its dark skin scraped off, leaving it pink and raw. But that is their natural coloration. If you want to see one in the pink flesh, they’re found in the Volcan Wolf region of the Galapagos, on Isabela Island. While this iguana is a species unto itself, experts say only around 100 of them known to exist.
And before getting to the number one critter, here’s an honorable mention. We found an interesting story about the Great Frigatebird which nests in the Galapagos. It’s not unlike the Magnificent Frigatebird which we mentioned earlier. In this species, the males also have a red sac at the throat which is inflated to attract a mate. We’re including it because this particular animal was involved with an unusual experiment to see if birds could actually sleep while flying. And while that has been suspected for some time, scientists now have proof of the phenomenon. The brainwaves of Great Frigatebirds were monitored for 10 days. Researchers found that the birds could in fact be half asleep, but kept one eye open (literally) to watch out for potential threats. The stats revealed that the bird subjects would sleep for just over 40 minutes while they flew on autopilot. But when on land, they will sleep for up to 12 hours a day. Experts say it’s an example of ‘unihemispheric sleep’ — where one half of the brain shuts down while the other half remains alert.
The world’s largest species of tortoise can weigh more than 900 pounds. That enormous size has helped make them so iconic, that the Galapagos Islands were actually named after these reptiles (not the other way around). They’re among the longest-lived vertebrates, with life spans documented up to around 170 years. Their population underwent a great decline from when they were first found in the 16th century. At that time their population numbered around 250,000 individuals. By the 1970s, only 3,000 existed. Today, there’s around 25,000, but the species is classified as vulnerable. Besides the Galapagos, giant tortoises only exist on the archipelago of Aldabra in the Indian Ocean.
When Lenin Moreno ran in the 2017 presidential election in Ecuador, he promised to continue the left-wing policies of his left-wing predecessor Rafael Correa. Correa, eg, had strengthened conservation policies for the Galapagos islands. However, once elected, Moreno became a stooge of the Donald Trump administration in the USA. Moreno annulled WikiLeaks founder Julian Assange’s Ecuadorean citizenship and asylum in the London embassy of Ecuador to pave the way for persecution of Assange by Trump in the USA.

From the University of Leicester in England:
Baby pterodactyls could fly from birth
Discovery shows extinct flying reptile had the remarkable ability to fly from birth
June 12, 2019
A breakthrough discovery has found that pterodactyls, extinct flying reptiles also known as pterosaurs,
had a remarkable ability — they could fly from birth. This discovery’s importance is highlighted by the fact that no other living vertebrates today, or in the history of life as we know it, have been able to replicate this. This revelation has a profound impact on our understanding of how pterodactyls lived, which is critical to understanding how the dinosaur world worked as a whole.
Previously, pterodactyls were thought to only be able to take to the air once they had grown to almost full size, just like birds or bats. This assumption was based on fossilised embryos of the creatures found in China that had poorly developed wings.
However, Dr David Unwin, a University of Leicester palaeobiologist who specialises in the study of pterodactyls and Dr Charles Deeming, a University of Lincoln zoologist who researches avian and reptilian reproduction, were able to disprove this hypothesis. They compared these embryos with data on prenatal growth in birds and crocodiles, finding that they were still at an early stage of development and a long way from hatching. The discovery of more advanced embryos in China and Argentina that died just before they hatched provided the evidence that pterodactyls had the ability to fly from birth. Dr David Unwin said: “Theoretically what pterosaurs did, growing and flying, is impossible, but they didn’t know this, so they did it anyway.”
Another fundamental difference between baby pterodactyls, also known as flaplings, and baby birds or bats, is that they had no parental care and had to feed and look after themselves from birth. Their ability to fly gave them a lifesaving survival mechanism which they used to evade carnivorous dinosaurs. This ability also proved to be one of their biggest killers, as the demanding and dangerous process of flight led to many of them dying at a very early age.
The research has also challenged the current view that pterodactyls behaved in a similar way to birds and bats and has provided possible answers to some key questions surrounding these animals. Since flaplings were able to both fly and grow from birth, this provides a possible explanation as to why they were able to reach enormous wingspans, far larger than any historic or current species of bird or bat. How they were able to carry out this process will require further research, but it is a question that wouldn’t have been posed without these recent developments in our understanding.
Dr Deeming added: “Our technique shows that pterosaurs were different from birds and bats and so comparative anatomy can reveal novel developmental modes in extinct species.”
