#FossilFriday: Geode Fossil

This is a beautiful geodized fossil – a sea snail fossil filled up by a yellowish calcite geode. The fossil is part of the Busycon genus – a genus of large, generally edible sea snails. These snails are commonly known in the United States as whelks or Busycon whelks. This fossil was reportedly taken from the Anastasia Formation in Florida, USA — a

Fossil friday: Platycrinus saffordi, the sea lily

Though they’re known as sea lilies, crinoids are animals not plants. Think of them as starfish-on-a-stick: they are filter-feeding sea floor echinoderms, and relatively common as fossils go. Crinoids as a group aren’t extinct, but are relatively uncommon in modern oceans.

Fossil Friday: Zaphrentis phrygia

Kinda looks like the Sarlacc, doesn’t it? Well take your geek hat off cause it isn’t a sarlacc. Now put your paleontology geek hats on because this is Fossil Friday and we’re talking about Zaphrentis phrygia.

Fossil Friday: Diptera brachycera in amber

Diptera are still alive and kickin’ today, and some of them are getting coated in amber as we speak! A nice reminder that fossils are still being formed for future paleontologists to uncover.

Fossil Friday: Dicranurus monstrosus

When a species almost one hundred times bigger than you, who has access to nukes and can go to space, discovers your remains a few million years after you die and still decides to call you “monstrosus” you must be doing something very right survival-wise.

Fossil Friday: Helicoprion

Helicoprion is an extinct genus of shark-like, cartilaginous fish that lived from the early Permian (~290 m.y. ago) all through to the massive Permian-Triassic extinction episode (roughly 250 m.y. ago.)

FossilFriday: Ammonite Growth Chambers

Ammonite fossils are among the most common in the world, with their characteristic shape and chambered shell. But did you ever wonder what the deal is with those chambers? Ammonites are a group of cephalopod animals that lived as swimmers in the shallow parts of the ancient oceans. They were extremely successful, emerging in the early Devonian 400 million years ago

Fossil Friday: looks like a squirrel, tastes like chicken, is actually a dinosaur

  This is without a doubt one of the most complete and one of the most spectacular dinosaur fossils ever found. It’s a small theropod dinosaur, a group of ancestral predators from the Mesozoic. Oliver Rauhut, who was one of the authors of the study that described the dinosaurs, writes: “It is a small theropod dinosaur (total length c. 70 cm)

#FossilFriday: Dunkleosteus

Dunkleosteus is an extinct placoderm fish that lived some 380 to 360 million years ago, during the late Devonian. It’s called a “placoderm” because its head and thorax was covered in armored plates – this was generally how fish were built in that time. The largest species, D. terrelli, measured up to 10 meters (33 feet). They were probably slow,

#Fossil Friday: Ordovician Edrioasteroidea

This is Streptaster vorticellatus, a member of the Edrioasteroidea class. The Edrioasteroidea is an extinct class of echinoderms that lived all the way on from the Ediacaran period 600 million years ago! However, Streptaster vorticellatus lived “only” 450 million years ago, during a period called the Ordovician. The body plan for this class was simple: a main body (theca), composed of many small plates, a peripheral rim

Fossil Friday: Opalized belemnite

Belemnites are an extinct order of cephalopods (“cephalo” meaning head and “pod” meaning leg) that lived during the Mesozoic era, some 200 to 65 million years ago. They were elongated organisms, resembling today’s squids, only tinier and cuter.

#FossilFriday: Ancient Fern

This is a fossilized Phegopteris guyottii – a species of fern. Its genus still exists today and is known collectively as the beech ferns. Ferns emerged in the late Devonian, some 360 million years ago. Many ferns still exists today, though most of their ancestors didn’t emerge until roughly 145 million years ago in the early Cretaceous, after flowering plants came to

Fossil Friday: Zhenyuanlong

This magnificent creature is Zhenyuanlong, a genus of dinosaur related to the velociraptor. Living approximately 125 million years ago, this specimen left behind a stunning fossil, with a nearly complete skeleton that contains traces of feathers, including long tail feathers and large wings. Yes, this animal had feathers, just like the velociraptor did – so write-off that image that Jurassic Park left,

Treasure trove of Permian fossils discovered in Brazil

The fossils were discovered in the Parnaiba Basin of north-eastern Brazil, and are some 278 million years old, corresponding to the Permian period, when all the continents we know today were still fused together.

Challenging the “Out of Africa” theory, one tooth at a time

Recent fossils unearthed in the Chinese province of Daoxian come to unravel the story of humanity’s spread as we know it today. The find consists of 47 teeth, belonging to modern humans, but what’s really important is their age – they have been dated to 80,000 years ago. This number doesn’t fit with the “Out of Africa” migration theory, holding that humans originate and have spread from the horn of the continent all around the world. The theory as we know it can’t explain human presence in the area for another 20,000 years.

Fossil Friday: Mesozoic Dragonfly

This is Parahemiphlebia – a dragonfly that lived over 100 million years ago, in the Cretaceous, and was contemporary with T-Rex and the Triceratops. The fossil was taken from the Crato Formation, in Brazil.

Fossil Friday: Peeking inside a beautiful Ammonite

We’re back this week… again with an ammonite! I know, I know, we’re doing ammonites more often than not, but I can’t help it if they just look so amazing!  

FossilFriday: A Magnificently Fossilized Stegosaurus

This is a fossilized in-ground Stegosaurus currently exposed at the Houston Museum of Natural Science. The Stegosaurus is one of the most easily recognizable species of dinosaurs, living until about 150 million years, and this remarkable fossil does a fantastic job at highlighting it. Ironically, although many people associate it with the T-Rex, the Stegosaurus is actually much more ancient. T-Rex

FossilFriday: Ancient sharkbite preserved in fossil whale bone

A fragment of whale rib found in a North Carolina strip mine is offering scientists a rare glimpse at the interactions between prehistoric sharks and whales some 3-4 million years ago, during a period called the Pliocene. Three tooth marks on the rib indicate the whale was once severely bitten by a strong-jawed animal. Judging by the 6 centimeter (2.4

#FossilFriday: Slab of sea-star fossils

It’s chique, awesome looking and really old – it’s the paleontological equivalent of a Louis Vuitton!
