The Naturmuseum Senckenberg in Frankfurt is the second largest museum of natural history in Germany. It is particularly popular with children, who enjoy the extensive collection of dinosaur skeletons: Senckenberg boasts the largest exhibition of large dinosaurs in Europe. One particular treasure is a dinosaur fossil with unique, preserved scaled skin. The museum contains the world's largest and most diverse collection of stuffed birds with about 2000 specimens.

Shown is a drawing from Williston (1898) that shows the skeletons of three common species of mosasaurs from Kansas; Clidastes propython, Platecarpus tympaniticus and Tylosaurus proriger. Although these three species are shown about the same size in the drawing, in life, Clidastes was the smallest (about 12-15 feet); Platecarpus was the next largest (about 24 feet) and Tylosaurus was the largest (30 plus feet):

This 31-foot “terror croc” ate dinosaurs. Now it’s back
predator museum United States Dinosauria skeleton
A massive, bus-sized “terror croc” that once preyed on dinosaurs has been brought back to life in stunning detail with the first scientifically accurate full skeleton of Deinosuchus schwimmeri. Stretching over 30 feet long, this ancient apex predator ruled the southeastern U.S. more than 75 million years ago—and now visitors can see it up close at the Tellus Science Museum, the only place in the world with this replica.

This 2-pound dinosaur is rewriting what scientists know about evolution
fossil Alnashetri Alvarezsauria Dinosauria bird evolution skeleton
A nearly complete dinosaur skeleton discovered in Patagonia is helping scientists crack the mystery of alvarezsaurs, a bizarre group of bird-like dinosaurs. The fossil of Alnashetri cerropoliciensis reveals that these animals became tiny before developing their later specialized features, such as stubby arms and ant-eating adaptations. Weighing under two pounds, the dinosaur is one of the smallest known from South America.

190-million-year-old “Sword Dragon” fossil rewrites ichthyosaur history
United Kingdom Jurassic fossil Ichthyosauria evolution skeleton
A newly identified ichthyosaur from the UK’s Jurassic Coast is rewriting part of the prehistoric playbook. Nicknamed the “Sword Dragon of Dorset,” the three-meter-long marine reptile lived during a poorly understood window of evolution when major ichthyosaur groups were disappearing and new ones emerging. Its beautifully preserved skeleton — complete with a blade-like snout and possible last meal — helps pinpoint when this dramatic transition occurred.

Mexico United States Late Triassic Triassic fossil skeleton
This week we will be checking out a relative of modern crocodilians that has tricked scientists multiple times!  Enter Hesperosuchus agilis!Hesperosuchus was a pseudosuchian (related to crocodilians) that lived in what is now Arizona and New Mexico, USA, during the late Triassic period, about 210 million years ago.  It would have been a meat-eater and from snout to tail the most complete skeleton measures about four feet (1.2m) but other fossils suggest it could have grown larger, up to about si

A lost disease emerges from 5,500-year-old human remains
Colombia evolution skeleton
A 5,500-year-old skeleton from Colombia has revealed the oldest known genome of the bacterium linked to syphilis and related diseases. The ancient strain doesn’t fit neatly into modern categories, hinting at a forgotten form that split off early in the pathogen’s evolution. This pushes the history of treponemal diseases in the Americas back by millennia and shows they were already diversifying long before written records.
