Photos and tales of past expeditions

Eagles

We are in the process of doing a survey of three locations in the region. We hope to identify enough species to establish a timeframe for the deposition of the fossils. Ms. Offutt, who once taught us biology in a classroom setting, joined us for the expedition. She is...

Brownie With Buddies

On an early Friday morning, some friends and I gathered into our car and went down to Brownie. I had not expected Finn and his dad to get up so early. Even on their first fossil-hunting expedition, they were so dedicated that they were ready to go at five o'clock. By...

Eichstaedt

We discovered the fossil richness of Germany in our visits to Eichstädt and Rügen. We traveled away from the city Nürnberg to explore for fossils. We were heading toward the Altmühl river valley, a valley that spanned multiple towns such as Solnhofen and...

KPg?

North Carolina. I got up early hoping to get to the stream first to claim the fresh fossils. I went downstream in hope of something new. I instantly hit pay dirt. The sand bar was about fifty feet across and full of gravel. The perfect location for a large deposit of...

Rügen

The thunderbolts of Rügen are orange, crystaline bullets. They are the remnants of ancient squidlike creatures, which became extinct with the dinosaurs. They are called belemnites. We stayed three days on the northern corner of Rügen where the clear blue waters of the...

Hidden coves

The tide was higher than usual along Calvert Cliffs. We had to wade through hip deep water to move from one cove to the next. We made good finds in the coves. Up on the edge of one beach where it met the cliff, I spotted a pristine snaggle. I picked it up. In the...

Old-School Brownie

I went back to Brownie with some high rubber boots. No robotics, just noodling around on the beach and clay matrix. We got there at about 7 o'clock to catch the 8:48 low tide. Soon after we passed the first bend around the cliffs we saw some interesting hunks of clay....

Visit to TU Delft

I visited TU Delft. I had prepared a presentation of Paleobot 2. Luckily, it wasn't too hard to find somebody interested in seeing my work. I met Proffessor Kooij and his grad students while they were having a break from work. They were a kind and receptive audience....

FTC World Championship

For two years I have participated in the FTC robotics program. Last year I wrote a computer-vision-based autonomous control. FTC stands for First Tech Challenge, founded by inventor Dean Kamen. It is for high school students. Unlike First Lego Legue, FTC robots are...

A Successful Autonomous Excavation

Paleobot 2 excavates fossil shark teeth on Friday the twenty-fourth on the Chesapeake bay. It is now operating fully autonomously. Paleobot stops and goes forth in a farming style. It inches along and picks up fossils when it sees them. Once it picks up the fossils,...

Paleobot Two field tests

This weekend (March 4th) I dragged my family to the beach to do some field tests for my robot. We visited a place in the Chesapeake bay commonly known as Brownie Beach. It was a great time for field testing due to a very low tide. This exposed more soil types so that...
